After hosting and judging 11 seasons worth of Project Runway, you’d think that Heidi Klum wouldn’t lose sleep over her new gig on America’s Got Talent.

Still, the supermodel admits to feeling a little overwhelmed as the new season of the hit NBC reality-competition series approaches.

“It is overwhelming,” Klum — who will join Howie Mandel, Howard Stern and Spice Girl Melanie Brown when AGT premieres this summer — told Celebuzzat the LA launch of her new active wear collection for New Balance on Thursday. “But it is so much fun at the same time!”

“I never know who’s going to show up next. [Every day] I’m looking at 35 different acts, from singing [to] juggling … Everyone is so different and unique.”

Klum joins Talent following Sharon Osbourne’s high-profile exit last year.

Meanwhile, the busy mother-of-four is adding even more to her plate with a new fitness line.

“I really think about every piece and how it will look on a women’s body,” she said of her collection. “As a woman, you always want to look good and you want your clothes to perform with you.”

They’ve got Talent, yes they do.

With Season 8 right around the corner, America’s Got Talent host Nick Cannon spoke out about his dream team for the judges’ panel.

“[Barbra] Streisand, Cher, call us. We’re ready!” Cannon told Celebuzz at the Cartoon Network’s Hall of Game Awards in Santa Monica, Calif.

When it comes to revamping NBC’s judging lineup on the reality competition, Cannon would love to “put some ladies in the mix” following Sharon Osbourne‘s controversial departure.

“That would be amazing. That’s what I’d aim for,” he said about the idea of bringing Streisand and Cher on board. “I think [the producers] should reach that far and get those people, absolutely.”

As for the male mentors, Cannon expressed his love for Howie Mandel and Howard Stern, who signed on for another season in December.

“I got the best judge in the game, Howard Stern. He and I can hold it down,” he said, adding, “I would love to see Howie [Mandel] back. I want Howie to come back. Howie’s hilarious and awesome on the show.”

Good news for Cannon: Mandel announced his return to the judge’s chair on Wednesday. (via USA Today)

In 2012, AGT was the No. 1 summer series on broadcast television, averaging between 10 and 12 million viewers for each of its three nights on air. With auditions underway, the reality show begins its first taping on March 4 in New Orleans.

Want to live like a star? Well, this is “Howie Do It!”

Former Deal or No Deal host Howie Mandel has relisted his prized Malibu mega-mansion for a whopping $7.75 million, hoping to win big in the real estate game.

According to records, the 57-year-old initially put the home on the market in December 2011 for $500,000 lower than its current price tag, but has recently bumped up his asking price.

What’s included for this new sum?

Designed by architect Douglas Burdge and located in the prestigious Point Dume area, the Cape Cod-inspired abode boasts five bedrooms, five and a half baths, an office, theater, gym and private guesthouse.

The home, built in 2009, features breath-taking panoramic ocean views and sits on over an acre of flat land with expansive lush lawns, a huge outdoor patio and stunning infinity pool.

NBC’s America’s Got Talent has had a tumultuous time keeping its own talent. Sharon Osbourne made a very public declaration in August that she wouldn’t be returning. But, news that Howard Stern had re-upped for another season broke last week.

But what about judge Howie Mandel? “I don’t know,” he admits to Celebuzz.

“They haven’t told me yet,” he continued. “They do the same thing every year. In January, they call me and let me know. I would love to come back.”

Mandel is still very thrilled by the job, but there’s one thing he doesn’t love about the gig: running down the aisle while being touched by the adoring audience.

The married father of three suffers from a host of maladies, which he chronicled in his book, Here’s the Deal: Don’t Touch Me. They include adult ADHD, OCD and a severe case of germaphobia.

He jokingly admits that he’s not that far from being naked in a hotel room peeing in a bottle ala Howard Hughes. The way he combats his numerous fears and neuroses is through medication and a lot of therapy.

“I’ve made a couple of therapists very rich over the years,” he says ruefully.

And as for those sprints down the aisle, “My therapist says that it’s good cognitive therapy for me.”

During the hiatus from AGT, Mandel is working on a new holiday game show, NBC’s Take It All, which debuted on Monday after The Voice. He describes it as The Price Is Right meets Deal or No Deal meets Jerry Springer.

The limited run show, which amps up the concept of Secret Santa with thousands of dollars of prizes climaxes with two contestants pitted against each other. They can either split everything, lose everything or have one person walk off with all the cash and prizes.

The 57-year-old comedian says that there has been copious amounts of wailing and gnashing of the teeth. “People are screaming and crying and fainting,” he gleefully told us.

The Canadian comedian says that after Deal or No Deal, he received offers to host several other game shows, but he declined. “I don’t want to ask trivia questions,” he explained.

The comic, who first became famous more than twenty years ago on the NBC medical drama, St. Elsewhere, also has Mobbed on FOX, which applies a hidden-camera spin onto the flash mob concept.

“I’m a comedian and I like to observe human behavior,” he said of his projects. “And also I’m like a viewer at home watching the show.”

Take It All airs all this week at 9PM with its finale next Monday at 10PM on NBC.

America’s Got Talent delivered its “Susan Boyle moment” this week with the debut of 10-year-old Jackie Evancho, who appears to be your average adorable little girl — until she opens her mouth. She wow-ed the judges with a goosebump-inducing version of the opera song, “O Mio Babbino Caro.

”As Got Talent judge Howie Mandel put it: “She’s a child, but she’s got the voice of a well-seasoned star.”

Hear Jackie’s jaw-dropping performance here:

A Burbank judge has approved a restraining order for Jennifer Love Hewitt against a 62-year-old stalker. TMZ reports that David Nolte has sent Love Hewitt over 100 letters detailing graphic and violent sexual fantasies involving the Ghost Whisperer actress.

TMZ reports that Hargitay also suffered the same problem over the holidays. Her rep says that she will not miss any episodes of her hit NBC show this season despite her medical issues.

Former supermodel and Project Runway host Heidi Klum is solidifying her reputation as a free-and-easy spirit.

Klum spoke to CNN about her upcoming hosting gig for this year’s Emmy awards with fellow reality-TV biggies Howie Mandel, Tom Bergeron, Jeff Probst and Ryan Seacrest.

According to Heidi, the most challenging—and satisfying—aspect will be the X factor involved in a live broadcast.

“The worst thing is that a lot of things can go wrong, but at the same time, that’s also maybe a good thing, because maybe you can use that to your advantage and make a joke out of it,” says Klum, who is also nominated for a statuette this year.

“I wouldn’t mind if one of the other guys would completely do some twisted thing on me and totally get me discombobulated and you kind of have to shift gears.”

Hmm; she wants a dude to do “some twisted thing on me”?

Sounds like the company she’s been keeping lately has been rubbing off on her. In every sense of the phrase.

With the 2008 Emmy Awards approaching in mere weeks, producers made the surprise decision to have all five Reality TV Host nominees share hosting duties throughout the night. 

When television hosting first began, only minor celebrities took on the role. The job has become much more desired in recent years, and has given many celebrities their fame.

Heidi Klum is America’s most beloved European from hosting Project Runway. Tom Bergeron started his hosting career on America’s Funniest Videos and is now well-loved on Dancing with the Stars. Ryan Seacrest has hosted himself into being one of the biggest sharks in show business. And everyone knows that Howie Mandel has germophobia after watching him shy away from handshakes on Deal Or No Deal.

Tune in on September 21 to see which fantastic host nabs the Emmy Award!

Heidi Klum from Project Runway, Tom Bergeron from Dancing with the Stars, Ryan Seacrest from American Idol, Howie Mandel from Deal or No Deal and Jeff Probst from Survivor—the five contestants for the newest Emmy category—will be sharing hosting duties for the Emmy awards show on September 21.

According to executive producer for the television event, Ken Ehrlich: “They were excited by this. They got it, what a fresh idea this was and how this could be fun for them,” Ehrlich told the press.

Last year, Ryan Seacrest played host for the awards show, giving him a clear advantage over the four other nominees.

Even though their hosting won’t affect the outcome for the Reality TV Host category, since the votes will have already been tallied, it’s still fun to imagine it will. Especially, if the nominees are suddenly tasked with a swimsuit competition.

The smart person’s money would be on Heidi Klum.
