As blizzard Nemo blasts across the East Coast, Hollywood is bracing for what could be a record-breaking whiteout.

Whether its sending well-wishes to those in its path, bemoaning thwarted travel plans, or quipping about the name Nemo — he’s finally be found! — celebrities are turning to Twitter as they wrap their head around the snowstorm that threatening to wreak havoc in wake of Superstorm Sandy.

While many New Yorkers brave the snowflakes for the sake of Fashion Week — from Heidi Klum, to Michael Kors, to Peter Facinelli — others in the Tri-state area are hunkering down in the warmth of their homes, from Ashley Greene in Manhattan to Nicole “Snooki” Polizziin New Jersey.

But NYFW isn’t the only show that must go on. Justin Bieber, who is slated for double-duty as host and musical guest on Saturday Night Live this weekend, rose bright-and-early Friday for rehearsals in NBC’s Big Apple studio. “up real early today…and now a blizzard is coming,” he tweeted. “no issue. Im Canadian.”

Now see how other stars, from coast to cast, are reacting to snowstorm Nemo on Twitter.

Charlie Sheen, eat your heart out. The actor’s ex, Denise Richards, 41, showed Sheen just what he’s missing when she bared her amazing bikini bod in L.A. this weekend.

Richards flaunted her incredibly fit figure at the SVEDKA Colada Beach House, complete with an afternoon of playing ping pong and sun bathing.

How do you think Richards looks in a bikini?

The mother of three has always been known for being genetically gifted, but her latest bikini outing still leaves jaws dropping.

Richards split with Richie Sambora, 53, back in June, as Celebuzz exclusively reported. The pair decided to end their rekindled romance after an ill-fated trip to Nashville, Tenn., for the CMT Awards.

Following a monumental blow-up, the relationship came to a close. “It’s over,” said a source. “They had an epic argument in Nashville and Denise told Richie she couldn’t continue the relationship.”

Now that Richards is single, perhaps Sheen can finally try to work things out with the mother of his two daughters, Lola, 7, and eight-year-old, Sam.

“She still looks f**king great,” Sheen, 47, has said. “Do I want to? Yeah! Does she? Don’t know.”

Do you think Richards should get back together with Sheen? Sound off in our comments section below.

Break-ups generally involve crying, fights, and the blame game. But occasionally you’ll get a couple that remains close after a sometimes-devastating split.

These celeb couples have learned to stay cool, calm and collected after the dust settles.

Just days before her ex-husband, Ryan Reynolds, 35, tied the knot to Blake Lively, 25, Scarlett Johansson, 27, was spending some quality time with another one of her exes, Jared Leto, 40. Leto was on hand to support Johansson during her 2012 Democratic National Convention speech and couldn’t hide his excitement for her.

Curious as to which other celeb exes are still friendly?

Rihanna, 24, and Chris Brown, 23, made major waves at the 2012 MTV VMA Awards when she kissed and hugged him while making her way to her assigned seat just a few aisles down. The singer also told Oprah on Oprah’s Next Chapter, “I think he was the love of my life.”

Meanwhile, Justin Timberlake, 31, and Cameron Diaz, 40, have remained friendly after their 2007 breakup. Thanks to the big screen, the two were reunited for their flick Bad Teacher and never once did things seem awkward. Diaz told People being on set with Timberlake was not a big deal. “We had a great time,” she said.

Angelina Jolie, 37, may be engaged to longtime boyfriend Brad Pitt, 48, but she’s always stood by ex-husband Billy Bob Thornton’s side. Jolie recently penned the forward to Thornton’s book, The Billy Bob Tapes: A Cave Full of Ghosts, where she explains that he “has a big beautiful heart.” Thornton, 57, has also had nothing but kind words for the mother of six and told ABC’s Nightline that they remain “good friends.”

David Arquette, 41, and Courteney Cox, 48, have been very candid about their mutual adoration for one another despite their ongoing marital issues. She dished to Jimmy Kimmel that even though the two are now legally separated, she and Arquette are “best friends.” The two also agree that their biggest priority is their daughter, Coco.

No matter how hairy a break-up can get, these couples are proof positive that you can get through things civilly and you may even end up becoming closer for it.

Which friendly ex-couple do you like the best? Let us know in the comments section below.

Denise Richards and Richie Sambora have split, Celebuzz has exclusively learned.

The pair decided to end their rekindled romance after an ill-fated trip to Nashville last week, where the Bon Jovi rocker, 52, was scheduled — but failed — to present on stage at the CMT Awards after a monumental blow-up, a source said.

“It’s over,” according to the insider.

“They had an epic argument in Nashville and Denise told Richie she couldn’t continue the relationship any longer.”

The 41-year-old Wild Things actress was scheduled to accompany Sambora – whom she reunited with last November after splitting in 2007, before going their separate ways again in January — to the CMT Awards at the Bridgestone Arena on June 6.

But she ended up walking the red carpet alone after Sambora cancelled his appearance and flew back to Los Angeles before the show even started.

When asked where “better-half” Sambora was, one red carpet source said Richards — who has three daughters, Sam, eight, and seven-year-old Lola, with ex-husband Charlie Sheen, and Eloise, whom she adopted in 2011 — quipped that her makeup artist was filling the role.

One Academy source told Celebuzz that Sambora initially told them he had to go home to take care of a personal problem with his 14-year-old daughter to ex-wife Heather Locklear, Ava, but later told one official that he was sick and needed to leave right away.

According to another source close to the situation, Sambora was unable to move past a jealous streak stemming from Richards’ close friendship with ex-husband Sheen.

Last week, the ex-Two and a Half Men star confessed in an interview to Rolling Stone magazine that he wanted to have sex with Richards again.

“She still looks f**king great,” Sheen, 46, was quoted saying. “Do I want to? Yeah! Does she? Don’t know.”

Sambora and Richards’ relationship-ending fight began at five-star Hermitage Hotel in downtown Nashville where another source reported hearing “Sambora screaming obscentities at the top of his lungs” from their ninth-floor suite.

He also appeared drunk when he walked through the hotel at one point, the source said.

“I was wondering what the problem was,” the hotel guest said.

As Celebuzz first reported, Richards and Sambora vacationed over Spring Break together in Hawaii, along with Ava.

If Heather Locklear and Richie Sambora are anything to go by, there may be a light at the end of the tunnel for recently-split celebrity couples like Jennifer Love Hewitt and Ross McCall, Katy Perry and Travis McCoy and Patricia Arquette and Thomas Jane.

Melrose Place babe Locklear, 47, and her rocker ex-husband Sambora, 49, were all smiles at their 11-year-old daughter Ava Elizabeth Sambora‘s View Point School soccer game in Calabasas, California.

Heather and Richie were married for just over 11 years. They split in February 2006.

However, the former couple have remained friends in the aftermath of their divorce. Locklear and her current beau, fellow Melrose Place alum Jack Wagner, 49, spent Thanksgiving with Richie and Ava.

“Heather and Richie are very supportive of each other,” a Locklear pal told People in November. “They talk all the time, and any time Ava has something important happening they are there together.”

That’s a great goal for both of them to keep in mind—well, that one, and the goal on their daughter’s soccer field!

Heather Locklear can’t wait for this year to end, and rightfully so. The past 12 months have seen the 47-year-old actress enter an Arizona rehab facility, only to be arrested and charged with DUI shortly after her release. (She faces a six-month sentence if convicted.)

Few people will be more relieved than her when that ball drops on January 1.

“I am really looking forward to 2009,” Locklear told Tonight Show host Jay Leno on Wednesday night’s program, Us Magazine reports. “There’s, like, three weeks left—I’ll stay in my house.”

While Locklear was on Leno’s show to promote her new Lifetime movie, Flirting With 40, the onetime Melrose Place resident’s recent personal woes dominated the interview.

Conceding that recent months have been “rough,” the beleaguered thespian nonetheless says that she sees light at the end of the tunnel.

“I’m good today,” she noted. “I think I am over that bump. I’ve done so much work.”

Well, clearly. Locklear spent Thanksgiving with her ex-husband, Bon Jovi guitarist Richie Sambora, 49, with whom she has an 11-year-old daughter, Ava Elizabeth. Also present: Locklear’s current beau, actor Jack Wagner, 49.

If she can be graceful under that kind of holiday awkwardness, Locklear can make it through anything.

Heather Locklear, 47, will not only be spending Thanksgiving with her 49-year-old boyfriend Jack Wagner, but also with ex-husband Richie Sambora, reports People.

Heather and Richie, 49, were both charged this year with DUIs, from separate incidents. They were married from 1994 to 2006, and have an 11-year-old daughter, Ava Elizabeth, together.

“Heather and Richie are very supportive of each other,” a Locklear friend tells the magazine. “They talk all the time, and any time Ava has something important happening they are there together. It’s going to be a very nice Thanksgiving for everyone.”

Meanwhile, the CW network has announced plans to revive Locklear’s hit 1990s nighttime soap, Melrose Place.

There’s no word yet on whether Heather will reprise her role as Amanda Woodward on the new version of the show, a la Shannen Doherty and Jennie Garth‘s return to the updated 90210.

On the heels of Richie Sambora’s March 25 arrest for suspicion of driving his Hummer while intoxicated, police have recommended that he be hit with child endangerment as well.

Make that some police. A TMZ update reports “a significant number of officers” disagree on the case’s overall charges: “There was no smell of alcohol on his breath, and no evidence of dangerous or erratic driving.”

Among Richie’s passengers were his and Heather Locklear‘s 10-year-old daughter, Ava, as well as her teenage cousin and his girlfriend Jenn Mallini of Girls Gone Wild apparel fame.

Cops are asking for a misdemeanor child endangerment charge, pending results of the Bon Jovi guitarist’s blood-alcohol test. The Laguna Beach D.A. has until Richie’s next hearing, on May 7, to determine if they will act on the police recommendation.

Either way, rest assured that somewhere in L.A., a steaming Heather Locklear is recalculating how her ex gives love a bad name while plotting her next move. Sole custody, anyone?
