Jennifer Aniston joined a friend yesterday for a business meeting in LA. She was on a break from filming her latest movie, Horrible Bosses, with a comb-over-sporting Colin Farrell and Jason Sudeikis. There was speculation that Jen and Jason had a relationship that went beyond purely professional, but she put those rumors to rest. The latest guy to find himself in the middle of Jen's love life is Christopher Gartin, who was the mystery man spotted at the Sunset Towers with her last week. Her rep said Jen and Chris are old pals who have had dinner "dozens and dozens of times," and Chris, meanwhile, had no comment.
