It’s a new house — and a new start — for Dianna Agron.

The Glee star just moved out of the rental she called home for almost two years in West Hollywood, Calif. — and she’s leaving all her baggage behind, a source told Celebuzz.

“She just bought a house,” the insider said. “And she left all the bad memories in the past, especially those of her exes, Alex Pettyfer and Sebastian Stan.”

Agron’s former digs — a three-bedroom, old Hollywood, gated abode that’s just seconds away from the famous Sunset Strip — rents for $8,500 a month.

It features a stunning chef’s kitchen with marble and granite countertops, high ceilings, French doors, spa-like bathrooms, and a master suite.

But all the furniture that made it home is staying right where it is.

“Alex and Sebastian spent a lot of time in the house with Dianna,” said the insider. “But now that her life is moving forward in a positive direction, she doesn’t want to bring any of the furniture with her — or any of the memories. She wants to put the past in the past.”

The 26-year-old actress dated Pettyfer, 22, after they met on the set of I Am Number Four in 2010; they split in early 2011. She then hooked up with Once Upon A Time hunk Stan, 29; they went their separate ways in December 2011.

Most recently, Agron has been spotted recently with director Henry Joost.

Agron moved out of West Hollywood rental just before Dec. 1. She isn’t the only famous face to have lived there: Lindsay Lohan and Liza Minnelli have also called it “home.”

Sebastian Stan has always had a thing for his leading ladies, only this time it’s serious.

The Political Animals hunk has been quietly dating his Once Upon a Time co-star Jennifer Morrison and friends haven’t seen him so taken with any of his girlfriends quite like this – even when it comes to his other famous ex.

“Sebastian is so happy,” a source close to the pair told Celebuzz.

Who is the other famous ex-flame?

“No one has ever seen him so smitten — not even with Leighton (Meester).”

Stan’s first high profile relationship was with Leighton Meester, who he met on the set of Gossip Girl. The pair dated for two years before splitting in 2010.

As was reported in July, Morrison, 33, and Stan, 28, have been seeing each other for over four months – and Celebuzz can reveal the happy couple is spending more and more time together.

And it looks like they may even be getting their own fairy tale ending.

“They’ve been in New York City together all summer,” said the source.

Like Stan, Morrison has also gotten close to another former co-star. She was engaged to her former House M.D. castmate Jesse Spencer.

Captain America star Stan most recently dated Glee‘sDianna Agron.

Politics in Washington D.C. has often been described as an ugly business, but it’s quite the opposite during this week’s episode of USA’s hit drama Political Animals.

Democracy takes a back seat in the fourth episode of the limited-run event when Sigourney Weaver’s character, former First-Lady-turned Secretary of State Elaine Barrish Hammond, debates the fine form of a fellow politician — with her sons and outspoken mother.

The characters played by Sebastian Stan, 28, James Wolk, 27, and Ellen Burstyn, 79, discuss who has the best abs on Capitol Hill.

So what’s it like to work on the set of the show?

Wolk — who plays an aide to his mother sat down recently with us in our Hollywood, Calif. studio and revealed what it’s like to work alongside the three-time Oscar-nominated actress.

When asked about filming some of the show’s tense scenes with Weaver, the actor said: “Let’s put it this way, when she acts, there’s no acting going on there, it’s just real.”

“When she gets intense in those scenes, you’re in there, and that’s someone getting intense with you,” Wolk said.

“So, yeah, it is intimidating, but as an actor, that’s perfect, because you don’t have to act. You just react. You’re like, ‘I’m scared as shit right now, and I’m gonna feel that.”

Political Animals airs Sunday nights at 10PM on USA Network.

This Tuesday is a huge day for Gleeks everywhere as the show’s Valentine’s Day special debuts on TV. Tonight, the cast is set to cover treasured love songs including Whitney Houston‘s “I Will Always Love You” and Gym Class Heroes‘ “Stereo Hearts.” 

To celebrate this special holiday, Celebuzz is taking a look at who has been stealing smooches from one of our favorite Glee gals. We know Dianna Agron has wooed Cory Monteith and Mark Salling on the show, but has the actress had any luck offscreen? You betcha!

In the past, Dianna has been linked to hunky actor Alex Pettyfer. The two became an item soon after they finished filming I Am Number Four together. The co-star couple split in 2011. 

Watch the video above to see more of Dianna’s past kissing connection!

We spy a special Gleek in the audience for the premiere of Captain America: The First Avenger! Dianna Agron, looking gorgeous while showing off her short blond hair in a dark one shoulder dress, supported boyfriend and former Gossip Girl star Sebastian Stan at his big premiere in Hollywood on Tuesday night, July 19.

Sneaking past most photogs on the red carpet, Dianna joined Sebastian and his friends and family inside the theater and was by his side when the film started to roll.

Agron wasn’t shy once she was inside, and snapped some pics with some fan girls waiting nearby when the film was over. Such a sweetheart!

After smiling and clapping when her beau hit the screen, Dianna waited in the front of the theater after the film finished for Stan before heading to the after party.

Sebastian was quite the talk of the theater! He had tons of people waiting for him to tell him congrats. Chris Evans of course does a fantastic job in the film, but Sebastian more than holds his own. 

Remember, Dianna was linked to Evans, Sebastian’s Captain America costar, but as we told you back in April it was totally exaggerated. Meanwhile, Stan’s last high-profile romance was with Leighton Meester.

We must say, what an adorable couple she and Sebastian make (walk of shames and all!). We approve! Do you? Sound off in the comments and be sure to follow Celebuzz on Twitter, Facebook and Tumblr for more young Hollywood news, pics and vids!

Sad news, celebrity-relationship buffs; Gossip Girl co-stars and real-life couple Leighton Meester and Sebastian Stan have reportedly called it quits on their fairytale romance.

A source close to the actress-turned-songbird says that Leighton was the one to pull the plug, because Meester “doesn’t know how to be in a relationship and doesn’t really like them.”

Oh, being in a relationship is simple, Leighton; you just find someone that you think is right for you, discover their flaws way too late, stick with them anyway out of a crushing fear of loneliness, and then spend the rest of your life in quiet misery.

Speaking of misery, Stan is said to be “heartbroken” over the breakup. Don’t worry, Sebastian; we’re sure there are plenty of ladies out there willing to help heal the ouchie on your heart.

From Gossip Girl chic to undercover extraterrestrial on the town. Yes, we realize how ridiculous this sounds, but what about how ridiculous she looks?

Leighton Meester was beamed into the opening event of the American Eagle flagship store in Times Square on Tuesday, thankfully leaving the mothership behind. We don’t understand, she’s usually donning a killer couture-esque look that only she can pull off. However, this time it appears as though she crossed the line and kept running. Not to point out the obvious, but she looks like she wet herself after eating a box of Crayolas.

The GG starlet attended the event with a few, more appropriately dressed, co-stars including Jessica Szohr and Michelle Trachtenberg. The cast watched as Meester rocked the stage in her deranged duds.

Earlier in the night she took to the carpet in a barely-there bondage-dominatrix look.

Relax, Gossip Girl fanatics; reports that GG actress Leighton Meester is engaged to her co-star and real-life beau, Sebastian Stan, have been greatly exaggerated.

Scuttlebutt began to emerge that the two became betrothed earlier this week, when the New York Post‘s Page Six gossip column ran an item claiming that the two had announced plans to wed on Facebook.

According to the Post, the couple, who began dating last year, both changed their Facebook status to “engaged.”

After the Post‘s item was published, cries of “OMFG” rang out across the blogosphere.

But it just isn’t so. Celebuzz has learned from very reliable sources that the two definitely aren’t engaged.

Apparently, they’re called “rumors” for a reason.

Which shouldn’t stop you from voicing your opinion on the matter. Have your say in the comments section: Do you think that Leighton and Sebastian should get engaged at some point?

According to Page Six, Gossip Girl‘s Queen Bee, Leighton Meester, 22, has gotten engaged to her boyfriend, Sebastian Stan, 25.

Stan and Reebok spokeschick Meester met on the set of the CW’s most scandalous show.  Their dating went public in July when they were spotted leaving a bowling alley at Chelsea Piers in New York City hand-in hand.

Meester has been linked with others, but it looks like ‘Bastian won out in the end.

Stan played the recurring character of Carter Baizen, a rival to Chuck Bass (Ed Westwick) for her character’s affections in two episodes of GG’s 1st season.

Stan is currently working on a series for NBC called Kings, which will update the story of David vs. Goliath for the modern age.

Meester and Stan are said to have updated their “secret” Facebook pages with the announcement. Guess the “secret part” didn’t work. Meester’s rep had “no comment” on the story which makes it sound fairly valid.

Sebastian obviously has no problem with Leighton’s parents’ shady past.

Meester’s character of bad girl Blair Waldorf has become the misunderstood villainess that the audience hates to love. One huge Samantha Ronson-type sexually inclined fan recently left a message on her non-secret, celebrity Facebook page which should indicate to Stan that he has some competition:

“omg blair or leight? hehehe i luv u so f***ing much! girl you are the reason for many thing i do in my life, i can’t say to u everything, every dream that i have with u, you are amazing, better: P-E-R-F-E-C-T! you rock and serena don’t ;)”

Stan better book the hall now before this chick comes calling. That’s some devotion!

UPDATE:

No one can predict the course of true love, but Us believes they have the inside scoop on the Leighton Meester and Sebastian Stan relationship.

A headline on the Us site trumpets, “Rep: Leighton Meester Is Not Engaged.”

However, a close reading of the tabloid’s story reveals that the rep doing the talking is Stan’s, not Meester’s.

Isn’t it traditional to let the woman do the talking when announcing or denying wedding plans?

Are they, or aren’t they?  Sound off in comments.
