Jennifer Aniston's accidental reunion with ex Vince Vaughn

Los Angeles: Newly-wed actress Jennifer Aniston had an accidental reunion with her ex-fiance Vince Vaughn when they ate dinner at the Sunset Tower here after the "She's Funny That Way" movie premiere.

The two had a short interaction and they appeared to be happy for the accidental run-in, reported Us Weekly.

"They were both jovial and seemed happy to see each other, both smiling," a source said.

Though they only had a short interaction, they didn't look awkward with each other. "It didn't seem weird at all, it just looked like two old friends who hadn't seen each other for a while catching up real quick," the source added.

Aniston and Vince began dating on the set of the film "The Break-Up" in 2005, following her divorce from Brad Pitt.

However, they called it quits in December 2006.
