Lindsay Lohan lived up to her mom Dina's promise that she'd have a "low-key" celebration in honor of her 25th birthday.

Dressed in tight white dress with hot pink platform, peep-toe heels, Lilo dined at Malibu favorite Geoffrey's. She enjoyed the restaurant's seafood specialties and headed home early.

Good job, Linds! Keep yourself in check, out of court, and on the straight and narrow!

With slightly longer hair (a la Mark Wahlberg in Boogie Nights) and a finely-tuned bod, Ben Affleck took his girls for lunch Saturday at Shutters in Santa Monica.

Recent reports have accused Affleck of being involved in an illegal gambling ring now targeted by a class action lawsuit on behalf of investors claiming their money was lost by a banker running a Ponzi scheme, playing with their dough at celeb-studded poker games.

Was yesterday's lunch perhaps a gesture of good-will toward wife Jennifer Garner? Further accounts of the gambling operation report "massage girls" and other unsavory characters held court with the group as they played card games with a $10K minimum buy-in.

You think Jen knew what was going on when Ben left the house at night?

Gwen Stefani and Gavin Rossdale are looking to their son Zuma to continue the family's rock-n-roll legacy. The 3-year-old is already banging away at his future career!

Stefani, of No Doubt and a super successful solo career, and Rossdale, the lead singer for Bush, took Kingston and Zuma to get new shoes Saturday and the store had a drum set for the kids to play with. Zuma was much more interested in making music than in buying shoes!

Check out the little boy's rhythm in the clip below ...

Now that Rosie Huntington-Whiteley is a big-screen star, the former model can afford to treat her action-flick boyfriend Jason Statham for a nice lunch!

The pair dined at Chateau Marmont Saturday for lunch and our photographer said there were more eyes on Rosie than on Jason -- and he's the one who used to be the bigger star!

Will there be competition between the long-time couple? We're guessing not ... the pair are building a house together in LA and plan to make Hollywood their home base. Seems there could be wedding bells in their future and maybe a few baby Rosies and Jason juniors running around!

LeAnn Rimes was as hot as the weather in Malibu Friday, dining out with a pal at Cafe Habana -- a new Cuban restaurant/bar owned by Cindy Crawford's husband Rande Gerber.

In a strapless, orange polka dot dress with her usual sky-high heels, LeAnn strutted her stuff at the Malibu Lumber Yard outdoor mall and one on-looker was overheard saying, "She's so skinny, but she's so hot!"

The second fiance Kris Humphrie's not around, Kim's got a new tall hunk to watch her back ... and we bet he was watching her back pretty closely!

Even in 5-inch platform espadrille wedges, this hottie towered over little Kim. And he sure was the gentleman Friday as Kim left her house -- holding the car door open for her and sticking close to protect her from the paparazzi ... What a good guy!

Transformers: Dark of the Moon the third installment in the action series by Michael Bay, pulled in $30 million Friday, putting its total domestic haul to-date at nearly $96 million.

Dark Moon, starring the new-to-the-trilogy Rosie Huntington-Whiteley and the series' star Shia LaBeouf, got a jump on the holiday weekend, opening Tuesday night in special 3D sneaks. The film's foreign box office is impressive as well, grossing $66 million through Thursday for an international total of at least $161.7 million, according to The Hollywood Reporter. The industry publication estimates the film could take in as much as $370 million, worldwide, by end-of-day Monday.

Meanwhile, the new Tom Hanks-Julia Roberts film Larry Crowne pulled in an older crowd, with 71% of the audience over 50!

On the flip side, Selena Gomez's Monte Carlo, grossed $3 million on Friday and 61% of its audience were under 25; 82% were female. The movie cost $30 million to make and is expected to bring in a low-teens figure by the end of the holiday weekend. Let's hope it will! Reviews, for the most part, have pitched it as a fluffy teen flick -- that said, it's that teenage disposable income so many marketers try to reach so maybe with Selena's name on it, the film can do just that!

Five-year-old Suri Cruise is an underage "it" girl, hanging at the Soho House in Miami on Friday.

The chic tot held hands with her friends (and their mommies) as she exited the members-only club, while mom Katie wasn't far behind to give her daughter a lift back to the car.

What a fashionable pair these two are -- Suri in her tulle-trimmed gray and pink skirt and mom in her wide-legged white jeans. But the little Cruise left her usual high heels at home in favor of some more comfortable flip-flops, which it was her pal who sported a more mature look with some black kitten heels.
