A few websites are reporting Kristen Stewart and Rob Pattinson are headed towards yet another break up, but then why is she carrying his brown puffer coat?!

On Saturday evening K. Stew was snapped flying in to Los Angeles International Airport from New York, and she was wearing her uniform of jeans, a tee and a cap, looking like her usual glum self. But back to that jacket! Rob was last seen wearing the coat at the German premiere of Breaking Dawn in December, so it looks like he let her hang onto it while they were apart for the last week or so.

While Rob will be busy with several films this year, Kristen is set to begin work on Focus, but she won't be starring opposite Ben Affleck. Last week Ben explained why he quit the flick, telling MTV News, "Basically I'm doing this movie called Live By Night and I'm trying to meet this schedule ... so that I can have it released at the right time. And basically I haven't gotten enough writing done; it became clear that if I took that job — it was in Buenos Aires for three months — I'd have to miss the deadline. I had to choose between getting the movie out when I wanted to or doing that movie ... Reluctantly I chose the latter but I love those guys, I love Kristen. I was really excited to work with her. I think the movie is going to be fabulous. I'm sure they'll find a great guy for it."

Hmm, think Jennifer Garner influenced his decision at all?

Britney Spears has given her three-carat diamond engagement ring back to former fiance Jason Trawick after confirming on Friday that the two had split, according to Us Magazine.

Trawick proposed to Spears in December of 2011 after the two had been dating for two years, and the ring cost approximately $90,000. Hey, at least she had the good manners to give it back! Plus, he probably needs the dough more than she does...

"Jason and I have decided to call off our engagement," the pop star said in a statement. "I'll always adore him and we will remain great friends." Trawick added, "As this chapter ends for us a new one begins. I love and cherish her and her boys and we will be close forever."

Apparently the couple ended their three-year relationship after having some discussions about children. According to TMZ, Spears reportedly wanted to expand their family, while Trawick is "in another place" and didn't agree.

Stacy Keibler went to the Gold For Golden event at Equinox in Los Angeles on Saturday afternoon to support Olympic athletes, and George Clooney's lady love looked amazing, but if the camera adds ten pounds, how skinny is she in real life? Yikes...

In other news, Stacy recently appeared in her beau's new tequila ad, and interestingly enough, Cindy Crawford and her hubby Randy Gerber also star in the spot. Randy is a partner in the Casamigos tequila venture, and while the video isn't NSFW, it's definitely a little more on the risque end!

Wait, what?!

On Saturday Seth MacFarlane and buzzed babe Charlize Theron were spotted leaving the Beverly Hills Hotel, and we don't want to suggest that these two are a couple, because last we heard, the Family Guy funnyman was dating the hot chick from Game of Thrones (Emilia Clarke a.k.a. Daenerys Targaryen), but we have to wonder!

Maybe Seth wanted some scoop on the Academy awards? After all, he'll be hosting them next month, and Charlize won Oscar gold back in 2003...

Jason Sudeikis and girlfriend Olivia Wilde are engaged!

According to a source for Us Magazine, Sudeikis proposed just after the holidays, and the insider added, "He finally found the one that made him want to commit. They've both been through it before and this has just felt right from the get go. Everyone is happy for them."

The couple were first linked in December of 2011, and both have been married before. Wilde was married to filmmaker and prince Tao Ruspoli for 8 years (the two split in 2011) and Sudiekis was previously married to actress and 30 Rock writer Kay Cannon from 2004 to 2010.

Congrats!

Ever since The Hills ended, it seems like we catch up with Lauren Conrad about 4 times a year! Not like we miss her that much, but it's always interesting to see what the reality star turned fashion designer is up to!

Lauren was snapped grabbing a bite at The Griddle in West Hollywood with a pal, and surprisingly, she didn't pull her usual duck and cover when she spotted photogs.

While the 26-year-old starlet has found some success with her novel series, it seems like she's always plugging her clothing collection these days. Hey, now that she's not making $120k per episode, she's gotta hustle!

Now that's hot!

Paris Hilton and beau River Viiperi jetted from Los Angeles to Mexico today, and not only did they travel with several pals, but the heiress got to meet her man's sister Luna for the first time.

After hopping off the plane, Paris immediately slipped into a bikini and struck a sexy pose. "The weather is beautiful," she tweeted. "Loves it! Can't wait to jump in the pool!"

Can't wait to see more photos from her vacay!

She may be a doting mother of three by day, but on Sunday night she's going to be all glammed up at the Golden Globe Awards!

And after that it's the SAGs, the DGAs, the BAFTAs and even though hubby Ben Affleck got snubbed by the Academy for a Best Director nomination, we have a feeling Jen will be by his side at the Oscars next month, as Argo is nominated for Best Picture.

Jen has been hitting the gym hard, and it also seems like someone has stepped up their game with styling Jen's daily wardrobe (and Ben's, for that matter), so we can't wait to see her red carpet looks over the next few weeks!
