She's getting on with her life.

A lot of people would shut themselves up in their house with a pint of Ben & Jerry's after a breakup, but Jennifer Aniston is not one of those people! The actress attended Jimmy Kimmel's wife Molly McNearney's birthday over the weekend, just a month after announcing she was splitting from husband Justin Theroux.

The Friends star mixed and mingled with pals Jennifer Meyer, Jason Bateman, Kristen Bell and Dax Shepard, and seems to be adjusting to the single life just fine. One famous lady that didn't score an invite? Jen's old pal-turned-enemy Chelsea Handler!

The A-list beauty and the comedienne had a huge falling out, and now Chelsea is relishing in her pal's misery.

"Chelsea didnโ€™t think much of Justin, but she said from the get-go that Jen would need to readjust her expectations and treatment of him if they were to stand a chance. But Chelseaโ€™s feeling pretty smug and โ€˜I told you soโ€™ about it now, to the point where she feels sheโ€™s owed an apology," a source dished to Radar.

Hey, looking good is the best revenge, so at least she's nailing that!
