Bradley Cooper was spotted with his girlfriend Suki Waterhouse at Spike TV's annual Guys Choice Awards Saturday.

The Hangover actor was rumored to have split with the 20-year-old British model just a few days ago, after he was recently spotted with a mystery woman in D.C.

"Bradley isn't returning any of her calls," a source told Star magazine. "The last text she sent asked him straight out if things were over, and he hasn't bothered to respond."

Seems like the couple have rekindled their romance because they were seen cuddling backstage at the awards show, sources said. 

The couple talked with Amy Adams, Cooper's co-star in the upcoming movie American Hustle. Sources revealed that they also mingled with Mark Wahlberg, Henry Cavill, Ben Affleck, Jamie Foxx, and Jessica Alba.

At the awards show, Cooper also ran into ex-girlfriend Jennifer Aniston backstage, The Daily Mail reported.

The publication noted that the Friends actress and Cooper chatted for a brief time while Waterhouse stood nearby. 

A source told People Magazine that Aniston and Cooper still keep in contact. 

"Jen always had a soft spot for Bradley, and she thinks he is very attractive and charming. Jen appreciates that Bradley is low-key, loves dogs and is focused on his movie career," the source said.
