Aww. Jennifer Aniston has moved on from John Mayer folks! Despite the public break up and the “leak” of John Mayer’s song “Heartbreak Warfare,” Jennifer was looking mighty happy at the David Lynch Foundation’s Paul McCartney concert this past Saturday night.

Gatecrasher reports that “She looked really happy,” said one witness. “There was a definite glow to her. She couldn’t stop smiling.” Which she did often at one lucky fella. “Jen checked out a cute guy walking in. She looked him up and down … twice! She flashed him a beaming smile but got pulled back into a conversation with her girlfriends.”

Aniston giggled with two gal pals, and was excited to see Sir Paul McCartney himself. “On a stage this size, it’s going to be great. I love him!” 

“She was having so much fun. John and their issues seemed like the last thing on her mind,” Gatecrasher’s spy shared.

On to the next loser I guess?
