Kate Hudson caught a flight out of LAX with fiance Matt Bellamy and her sons, Ryder and Bingham on Saturday, and the 33-year-old actress was all smiles as she strutted through the terminal.

While Matt has been busy touring with Muse, Kate has stayed in L.A. for the past few weeks with her boys. She recently wrapped production on the upcoming HBO movie Clear History, starring Larry David, Eva Mendes, Michael Keaton, Jon Hamm, Danny McBride, and Bill Hader. The flick follows a "disgraced former marketing executive who plots revenge against his former boss who made millions from the electric car company the once owned."

And who can forget the last time we saw Kate at the Golden Globes in a sexy black Alexander McQueen gown ... mama's still got it!

There may be a ban of sorts on super sexy attire at the Grammys this year, but that's not going to stop some stars from showing all sorts of skin at the pre and after parties!

Miley Cyrus attended the pre-Grammy bash honoring super producer/former X Factor judge L.A. Reid at the Beverly Hilton on Saturday night, and the starlet left little to the imagination in her black Emilio Pucci gown. Thankfully she wore pasties on her nips, but at several points during the evening her dress nearly slipped out of place and exposed her boobies. But hey, she looks amazing, so even if she did have a wardrobe malfunction, we'd still love her...

Miley struck poses with everyone from Nicole Richie to Katy Perry to Whiz Khalifa, and Katy was snapped snuggling up to beau John Mayer ... Click the gallery below for more pics!

Justin Bieber hosted Saturday Night Live last night, and not only did he take part in a hilarious skit where he totally bashes himself, but he also addressed the recent photos of him smoking pot.

During a sketch titled "The Miley Cyrus Show," Biebs played a fan of the blonde pop star, and he talks trash about Bieber, saying he's a "douche," that he looks like "a lesbian" and finally, that "he still has his baby teeth." After that mannequin make out session the other day with Jimmy Fallon, it's pretty clear that the kid has a good sense of humor!

So what about the party pics of Biebs puffing away on joints and blunts? Bieber, while still in character, added, "I also heard he got busted for smoking weed, and he's really sorry about it, and that people make mistakes, and he's never going to do it again."

Really? He'll NEVER do it again? Or he's just going to be even more careful about getting caught?

Check out his hilarious Valentine's Day monologue below, and click thru for his performance of "As Long As You Love Me"!

Christina Aguilera got lunch on Saturday in L.A., but before putting her order in she had to tie up her beloved pooch outside. She seemed fine, but the poor doggie looked like she had a serious case of separation anxiety!

Speaking of anxiety, Christina has one less thing to worry about these days as her ex-husband, Jordan Bratman, has finally moved the last of his things out of the Beverly Hills home they once shared.

Jordan originally refused to move following their divorce in October of 2010, but by January of 2011, he finally got his own place. However, he still had a ton of junk at the pad, but now that Christina is selling the house, it looks like he was forced into picking up the rest of it. What a relief for Xtina!

On Saturday Chris Brown totaled his black Porsche, and we'd assume this would cause the R&B singer to go on the warpath, but it looks like Rihanna was able to calm him down when the two met up at SoHo house immediately after the accident. Chris was later seen chatting with some pals outside, and he appeared quite animated, but he didn't look like he was going to throw a chair through a window. Always a good sign!

Chris was en route from the Debbie Allen Studio in Los Angeles for a Symphonic Love Foundation event, and according to police, he crashed his car into a wall in Beverly Hills because he was trying to elude the paparazzi. Chris said two vehicles cut him off and photographers jumped out and snapped his picture, and his rep added, "Chris' vehicle was totaled due to this aggressive pursuit by the paparazzi. He is okay." Chris was neither arrested nor cited, and his car was towed from the scene of the accident.

Chris may still be getting into trouble for punching fellow R&B stars and allegedly skipping out on court mandated community service stemming from his 2009 assault on Rihanna, but the funny thing is, the two seem to be better than ever lately. Not only did she accompany him to court on Wednesday and comfort him after the crash yesterday, but rumor has it they're going to the Grammys together tonight!

RiRi was at SoHo house for RocNation’s Pre-Grammys brunch, and Jay-Z and Beyonce were among the famous faces in attendance as well:

On Saturday Jessica Biel went shopping in Beverly Hills, and the 30-year-old actress looked stunning in a sleeveless floral dress.

We haven't seen much of Justin Timberlake's wifey lately (even when she was promoting Playing For Keeps), but we're guessing she'll be on his arm at the Grammys later today!

After all, JT is set to perform at the show, and this will be his first musical appearance since 2006! (He did perform at the DirecTV Super Bowl pre-party last weekend, but that wasn't televised.) Can't wait to see what she wears!

On Saturday Ryan Phillippe was snapped leaving lunch with his kids Ava and Deacon, and while they were waiting for their car, we snapped Ryan's son giving him a bear hug. Aww!

When the 38-year-old actor hasn't been on daddy duty (with his children with ex-wife Reese Witherspoon or his 17-month-old daughter with ex, model/actress Alexis Knapp), he's been hitting the gym and promoting his new documentary Isolated. The film follows five surfers who travel to New Guinea in search of untouched waves, but ended up discovering all sorts of disturbing things. Not to spoil the movie, but there is cannibalism involved. Yikes!

Everyone's going out to eat, huh?

On Friday night, Jessica Alba and hubby Cash Warren continued the celebrity dine out trend as they enjoyed dinner at Wolfgang's Steakhouse in Beverly Hills.

The 31-year-old actress, who looked pretty casual in a cute grey jacket, blue jeans and a pair of wedge trainers, has been busy with her motherly duties along with running The Honest Company.

She's also in final negotiations to star in the film Weightless, an original screenplay from Academy Award-nominated writer and first-time director Milo Addica (Monster's Ball) where Alba will be set to play aspiring female astronaut Maysie Overall.

She has a lot on her plate!
