Jennifer Garner and Violet snuck in some girl time at the Long Beach aquarium yesterday while Ben Affleck is away at the DNC like so many other celebrities. Last night he hosted a poker tournament, which brought out friends like Sarah Silverman about whom Ben joked to Extra, "Well, I’ve been dating her ex-boyfriend [Kimmel] for sometime. Other than that, we get along really well." While Ben is busy having fun and getting political, Jen is proving that big heart isn't reserved for Violet — she's yet another celebrity who will be attending the Stand Up to Cancer event.

Brody Jenner turned 25 last week, and to celebrate he packed up his favorite starlets and headed to Mexico to celebrate. Audrina and LC slipped into their bikinis to hit the beach at the LG Villa in Cabo before partying until the wee hours with margaritas and birthday cake. Guess these kids can afford the works considering how much they're getting paid. Looks like this trip was all about relaxation with minimum drama, so it was a good thing Heidi, Spencer, and their shopping cart of love weren't invited.

Chris Brown and Rihanna stopped by a Ferrari dealership in Beverly Hills yesterday before Rih put on a sparkly dress to party at Villa. The newest on the secretive couple is that they are looking to move in together. These two are attached at the hip these days, so we wouldn't be surprised if they found some new digs. We wish they'd take their relationship public, but until then we're hoping they show off their moves together on stage at Fashion Rocks next week.

Flynet and Ramey

The Entourage cast had a blast filming in NYC earlier today. They were seen hightailing it out of a club — knowing them it's probably to avoid some sort of trouble they caused — after heading to Queens to shoot some scenes earlier this week. Sounds like a homecoming is in the works for the guys, and you can get a sneak peek of the new season here. Between takes they caught up on the day's news like Hillary's big convention speech last night. While Vinny's always got his boys close by, we keep spotting Adrian out with pretty girls when the cameras stop rolling. Must be helpful to have a hit show to keep your mind off an ex.

Katie Holmes slipped into a LBD last night to check out her fellow Broadway stars at a performance of August: Osage County in NYC before heading back to rehearsals this morning. Tom and Suri didn't join her this time, but they're sure to be front and center on her opening night, and it sounds like there may be another familiar face in the audience too. When asked about checking her out on stage, her former costar and boyfriend Joshua Jackson said, "Of course! Of course!" While we'd love to see Tom and Katie on a double date with Josh and Diane, for now we're just happy to hear that the old Dawson's Creek kids are still so supportive of each other.

Heidi Montag greeted the paparazzi with open arms while shopping with Spencer Pratt today at Gelson's grocery store in LA. The couple shopped and smooched, and Spencer checked out Heidi's melons for a photo shoot almost as ridiculous as her new music video. They even had a fake sword fight with gift wrap, a little reminiscent of their virtual knockout match. With these two attention-seekers, it's no wonder LC thinks Heidi and Spencer chase after drama.

Lots more photos of Spencer and Heidi's ridiculousness so just read more
