Mother of three, Victoria Beckham, struck her traditional smile-free stance while walking her sons, Cruz, Brooklyn and Romeo Beckham to the Los Angeles restaurant, Fogo de Chao.

The stylish gang stepped out to celebrate Romeo's 7th birthday and the always animated Cruz Beckham didn't disappoint photographers as she made faces and showed off his unique fashion sense in a pair of trendy red sunglasses, Adidas tennis shoes, an astronaut costume and a star shaved into his hair.

As for Victoria and her constant stoic expression, the former Spice Girl tells Elle magazine for their October issue, "I do have my insecurities. Maybe that's why I look a little bit serious." Of the red carpet, she says, "I want to get in there, do what I've got to do, and get home to my kids." Well, hopefully, she enjoyed some smiles once she got inside the restaurant.

Soccer great David Beckham is seen here arriving at LAX with his son Brooklyn Beckham. While he's back in Los Angeles for now, don't look for Becks to be staying long.

David Beckham has confirmed that he fully intends to return to AC Milan for a second loan stint in January.

Beckham has been told he must continue to play top-level European football if he is to keep his place in the England squad for next summer's World Cup finals.

"It's simple. I want to return to Milan and Milan have said they would be happy to have me back," Beckham told La Gazzetta dello Sport. "If it's all right with Milan and it's all right with me, I don't see what problems there could be.

It hasn't been easy for David here in the United States, and he's much more beloved in Europe than he is in the U.S. The only problem may be if wife Victoria Beckham keeps on judging for American Idol.

Enjoying some downtime, David Beckham took his sons sons Brooklyn, Romeo and Cruz to The Grove shopping center where they picked up some new clothes. David carried little Cruz on his shoulders and Cruz, donning some slick contemporary sunglasses, practiced some karate chops for the photographers.

Hopefully David was able to avoid being heckled while shopping.

I couldn't think of a better cameo for the Sex and the City sequel than one from Victoria Beckham. The 35-year-old singer is believed to have been approached to play a fashionista in the new film when shooting begins next month.

Posh has previously revealed that she was offered a part in the first movie - but turned it down because filming clashed with rehearsals for the Spice Girls reunion tour. Now she's just busy planning the role of housewife back in Los Angeles.

I want a scene between Vicky and Samantha. That would be tons of fun.

Unable to find as much success in her foray into fashion in Los Angeles as she did in her native Europe, Victoria Beckham is reportedly eager to make a move to Milan. A source told the Daily Mail, "Victoria is going off LA and was embarrassed that her designs didn't take off there."

Now that hubby David Beckham will be returning to the U.S. to wrap up his pricey contract with the Los Angeles Galaxy, the Beckham clan are planning their next move.

Another snitch reveals, "Victoria hated the idea of moving to Milan at first but she's warmed to it." The Spice Girl with the penchant for severe fashion statements has been checking out properties in the area should David sign with AC Milan next season.

She's also been jamming tennis balls into the shoulders of her jackets, from the looks of it. How did this outfit not raise a terror alert at the airport?

Before his kids returned to the Los Angeles, soccer star David Beckham managed to squeeze in some quality time with his three boys Brooklyn, Cruz and Romeo Beckham. David gave his sons some pointers in soccer while they ran around on the training ground for AC Milan.

A witness reports, "It was fantastic to see them having so much fun. The boys were obviously thrilled to be reunited with their daddy. They must miss him so much."

Yes, David. So do we. Come back to Los Angeles. We promise to be good.

Although she rarely cracks a smile, mother of three Victoria Beckham is rarely happier than when she's spending time with her sons, David, Cruz and Romeo Beckham.

Photographers spotted the quartet making their way through Heathrow airport on their way back to Los Angeles from a stay in Milan on a visit to see their father David Beckham.

With two boys carrying a soccer ball in hand and all three sporting their professional athlete father's good looks, the boys clearly take after their dad. But that doesn't mean they don't enjoy the occasional shopping trip with Mommy.

Cruz Beckham is one superhero who doesn't mind revealing his multiple secret identities. The son of Victoria and David Beckham put on his Wolverine costume to head out to the XMA Martial Arts in North Hollywood to celebrate his fourth birthday. I'm sorry Hugh Jackman, but no matter how many crunches you do, you will never be this adorable.

Sporting a Batman costume, middle brother Romeo dressed up as his favorite crime fighter as well. But it was oldest son Brooklyn, who dressed up as his idol, wearing a LA Galaxy soccer uniform.

The kids look happy to be out for lunch at Gordon Ramsay's restaurant in Claridge's in London, but Victoria Beckham and Italy's finest David Beckham look like people do when they have to move from their third floor walkup to a fourth floor one. Damn, everyone hates the holidays but mask it for the kids! Here's the Beckham family out to Christmas Eve lunch with lil' Romeo, Brooklyn and Cruz.

Brooklyn wore jeans and a sweater under his coat, and he seems like the one who's going to end up emo and hating his life when he's older. He just should hit a pap and get it over with.

Do you ever get the feeling that these two are kinda "eh" about each other, but realize that they can keep raking in the millions if they stay together? Is it a British thing? You just never see them smiling or joking. Maybe it's all the high fashion. Some of the swag they wear probably isn't comfortable so it probably makes them all uptight and joyless.
