David Beckham was joined by all three sons, Brooklyn, Cruz, and Romeo, at LA's Staples Center last night. The foursome watched courtside while the LA Lakers squared off against the Phoenix Suns. Kobe Bryant and Dwight Howard led the team to a 114-to-102 victory over the visiting squad. David kept the boys occupied during breaks from game play and even posed for some adorable photos with Cruz while Brooklyn and Romeo played photographer. Earlier in the week, he made sure to spend some quality time with Harper as well. David and Harper visited The Grove where they played with bubbles and checked out the holiday decorations.

David's comfortable posing in front of the camera — in fact, he strips down once again in his latest H&M campaign. In addition to representing the fashion retailer, David's also added a new client to his modeling portfolio. Beckham is the new face of Breitling, and according to the soccer star, he chose the watch company because "they create not only the highest-performance watches but also timeless designs that have inspired generations. It was a natural choice for me to partner with this fantastic brand."

Justin Bieber and Selena Gomez were spotted together last night outside LA's Yamato restaurant. The couple were reportedly only there for a few minutes before exiting and driving off in separate cars. Justin and Selena reportedly ended their relationship last week after his performance at this year's annual Victoria's Secret fashion show. Shortly after rumors of the split emerged, the pair were then spotted at Selena's NYC hotel. She was in the Big Apple for Glamour's Women of the Year Awards while Justin performed a show in Boston over the weekend.

Both Selena and Justin have since returned to the West Coast for work obligations. Selena teamed up with Ryan Seacrest on Thursday at the opening of Seacrest Studios, and Justin's been prepping for his performance the American Music Awards. It seems Justin's still trying to figure out how to deal with balancing his personal and professional life and last night took to Twitter to share a message with his fans. Justin tweeted, "Things aren't always easy. There is a lot of pressure. I'm figuring it all out. I'm trying. But I care, I notice, I still hear you." We'll have to wait and see if Selena joins Justin at the AMAs. Last year, the pair hit the red carpet together and put on a memorable showing of PDA — do you think Selena and Justin can make it work?

Miranda Kerr showed off her legs in a short mini, leaving an appointment in NYC yesterday with Flynn Bloom. The pair have been spotted all over the Big Apple in recent days while Miranda takes care of business. She's been attending meetings all over the city in between high-profile modeling gigs. Miranda stopped by Vogue earlier this week and attended an intimate dinner thrown by W magazine. Miranda's been able to enjoy a bit of free time with Flynn, too. The mother-son duo appears to be enjoying the chilly temperatures on the East Coast: Miranda even snapped a few photos of Flynn playing in the snow. Miranda and Flynn are keeping bundled up during their daily adventures — however she strips down to her sexiest lingerie in this year's annual Victoria's Secret holiday runway show. You can see Miranda and her fellow Angels strut their stuff down the catwalk when the special airs on CBS Dec. 4.

Stars were out in full force this week, hitting the red carpet for premieres, filming on set, and attending black-tie affairs. Kristen Stewart wore a sheer gown to pose with Robert Pattinson at the LA premiere of Breaking Dawn Part 2, while Kate Middleton attended Remembrance Sunday services in London. Jennifer Aniston and fiancé Justin Theroux stuck close while celebrating the American Cinematheque Awards in LA, and across the pond, Brad Pitt got bloody with costar Mireille Enos to film reshoots for World War Z.

That's not all of the fun had by celebrities this week, so be sure to click through the rest of the exciting snaps!

The Wanted were among the performers who went through rehearsals in LA yesterday, prepping for Sunday's American Music Awards. All five members of the band — Max George, Nathan Sykes, Tom Parker, Jay McGuiness and Siva Kaneswaran — made it to sound check before jetting off to Hollywood's Roosevelt Hotel where they celebrated Siva's birthday.

Pitbull and Swizz Beatz also made it to rehearsal and are among the acts scheduled to take the stage this weekend along with Taylor Swift, Justin Bieber, Usher, and No Doubt — just to name a few.

Sienna Miller made sure to keep her head warm NYC yesterday, hailing a cab in a furry, hooded jacket. She's been spending a fair amount of time on the East Coast recently with daughter Marlowe and fiancé Tom Sturridge. Sienna's prepping to return to film opposite her former G.I. Joe: The Rise of Cobra costar Channing Tatum. Channing and Sienna previously played an engaged couple, but this time they'll have family ties in Foxcatcher. The drama tells the story of John du Pont, played by Steve Carell, who in 1996 killed Olympic wrestler David Schultz, played by Mark Ruffalo. Sienna's set to take on the role of Ruffalo's wife with Channing playing his brother. Production is scheduled to begin soon with the film tentatively planned for Fall 2013 release.
