Jimmy Kimmel's wife, Molly McNearney, turns 39 on Tuesday and celebrated early with a star-studded birthday bash. Aniston was among those at the party, and posed for a photo with McNearney, Jen Meyer (Tobey Maguire's estranged wife), Amanda Aanka (Jason Bateman's wife) and manager Aleen Keshishian, who reps the 49-year-old actress.
The Friends star looked gorgeous and relaxed in the image, with her hair down in loose beach curls, and sporting a sexy black slip ensemble that she paired with a long gold necklace.
While it was a ladies' night for Aniston, it was date night for other celebrities at the soiree. Kristen Bell and Dax Shepard also struck a silly pose in the photo booth as well as Bateman and his wife.
"HAPPY MOLLY'S BIRTHDAY EVERYONE!!! @mmcnearney is one of the kindest, most authentic, cleverest gals I have ever come accross," Bell captioned one of her party pics. "Her intelligence is only out shined by her wit. The world is better with her in it. I LOVE the fact that she exists. This is a very special day."
Bell also shared a video of McNearney, who is a writer on Jimmy Kimmel Live, dancing to 50 Cent's 2003 hit, "In Da Club," while her guests cheered and Kimmel sweetly stood next to her with a huge grin on his face.
As for Aniston, she appears to be keeping a pretty active social calendar since her recent split from husband Justin Theroux.
Last month, she made her first public appearance since announcing her separation from the 46-year-old actor-writer when she showed up to support Bateman, her friend and frequent co-star, at the premiere of Game Nightin Los Angeles, California.
Coincidentally, Bell and Shepard were also at this event.
