Emma Stone looked lovely in period clothes on the set of her new pic, The Gangster Squad, in Los Angeles on Saturday.

In the film, Stone is reuniting with Crazy, Stupid, Love co-star Ryan Gosling -- they play love interests again!

At least they're past that "awkward first kiss" stage. And both are dating other actors (and co-stars) anyway -- Ryan is hooking up with The Place Beyond the Pines co-star Eva Mendes, while Emma is dating The Amazing Spider-Man leading man Andrew Garfield.

Apparently the lot is not just for dancing -- David Arquette suited up (in a retro, pinstripe suit, that is) to hit a few golf balls at Dancing With The Stars rehearsal on Saturday.

Cameras were rolling as Arquette turned the parking lot into a driving range -- can't wait to see that on the show!

The suit is part of a costume for David and partner Kym Johnson's upcoming jive performance.

Camille Grammer, 43, has finally brought out her new beau -- bankruptcy attorney Dimitri Charalambopoulos (what a name!)

We got video of the two, though 35-year-old Dimitri doesn't seem as into the limelight as Camille. He stays largely out of our camera's way!

The two have been together for a few months, says the Real Housewives of Beverly Hills star. She finalized her divorce from Kelsey Grammer in February.

Jennifer Garner picked up daughter Violet from ballet class in Brentwood on Saturday, and little Violet was grinning from ear to ear!

We're betting she can't wait to be a big sister again. Violet, 5, has younger sis Seraphina, 2, but mom Jen's baby bump is growing bigger by the day!

About a month ago, Garner, 39, announced she was pregnant with her third child. She chatted with Ellen DeGeneres about her pregnancy in an interview set to air Tuesday, saying:

"Three girls is a great way to grow up. I'm one of three girls and my little sister is awesome. ... It would be so weird to have a boy."

But, Jen admitted that she'd be happy to have a son -- and so would hubby Ben Affleck, 39, because "he likes baseball and all that stuff."

Ryan Gosling paid a late-night visit to ladylove Eva Mendes' Los Angeles home Saturday night, and almost got busted by her security guards!

When a patrol saw Gosling's classic car parked outside of Mendes' place, they investigated. Eva had to come out to assure the guard that she was OK!

Eva tells the guard the car belongs to "a friend." Her security was right to be on high alert -- Eva has had issues with stalkers this year, and last week stopped at a police station after she became fearful that a car was following her around Hollywood.

But, looks like the only crime here is one of passion! Watch Eva talk the guards down in our exclusive video above!

Pump iron much??

Dancing With The Stars is known for helping certain celebs lose weight (Ricki Lake and Chaz Bono are this season's biggest losers so far), but since Elisabetta Canalis didn't really need to lose weight, the rehearsals are apparently giving her a ridiculously buff bod!

George Clooney's ex showed off her toned arms as she left practice in LA on Saturday. The flowing dress is quite a contrast to the glowing guns.

Celine Dion is a fairly private megastar, but she's opening her life up completely in a new doc for Oprah Winfrey's OWN network -- Celine: 3 Boys And A New Show.

We're not too hot on the title, but the 90-minute special looks good! Celine seems to have given rare, total access to the camera crew -- they're with her in the hospital when she gives birth to twins Eddy and Nelson, born in October 2010, and follow Celine home after to her $20 million Florida estate.

Celine said she did the special to show fans that she's not that different from them, and so that they could see the hard work that goes into putting on a Vegas show. Celine, 43, starts a new run in Vegas in December.

Dion tells cameras she's grateful for her 69-year-old husband, Rene Angelil. "It's tough to live with me," she says. "I'm not easy. I'm intense in everything that I decide to do."

Molly Sims has tied the knot with producer Scott Stuber.

Stuber and Sims dated for a year-and-a-half before he popped the big question in May. The couple exchanged vows in front of friends and family in Napa Valley, Calif., on Saturday, her rep confirms.

Sims, 38, wore a dress by Marchesa and jewels by Lorraine Schwartz, while her man, 42, sported a suit by Tom Ford. Guests, including Vince Vaughn and Josh Duhamel and wife Fergie, enjoyed red velvet cake at the reception.

Sims has never been married, while Stuber is once-divorced, but one thing the couple do share? Work ethic! Sims, a supermodel-turned-actress, is next hosting Project Runway spinoff Project Accessories. Stuber, who has produced flicks like The Break-Up and Role Models, has 40 projects -- yes, 40 -- in the works!
