Jennifer Aniston was grinning like a Cheshire cat as she checked out men at a recent charity event, according to a new report.

The former Friends star - who parted ways with ex-boyfriend John Mayer last month for his alleged Twittering ways - was reportedly on the prowl for new meat at David Lynch Foundation’s Paul McCartney concert Saturday night.

An onlooker tells New York Daily News, “She looked really happy. There was a definite glow to her. She couldn’t stop smiling."

The source adds, “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.

“She was having so much fun. John and their issues seemed like the last thing on her mind.”

Meanwhile, it is believed that Jen is keen on dating a sports star following a string of failed relationships with actors and musicians.
