Jennifer’s mystery man from Thursday has been identified as actor Christopher Gartin! Chris and Jen enjoyed dinner together yesterday evening at Jennifer’s favorite spot — The Terrace at Sunset Towers Hotel.

Not coincidentally, Gartin is a pal of Courteney Cox’s — in fact she even promoted him back in ’07 by slapping this bumper sticker on her car!

Chris starred with Courteney’s hubby David Arquette in the 1996 film Johns and apparently, a relationship developed from there. There was only one little bump in the road to bringing Chris and Jen together … Chris’ wife!

Gartin was married to Australian-born event planner Joanne, but since those two eventually divorced, Courteney was free to make the introduction to her hot friend Jennifer Aniston! (Not your average set-up!).
