When it comes to introducing new “friends,” it seems as though Jennifer Aniston’s been holding out on us for several weeks. The pretty forty-something star finally put an end to the rumors and stepped out with new beau and “Wanderlust” co-star Justin Theroux.Jennifer Aniston and Justin Theroux decided to make their romance public when they showed up together at the MTV Movie Awards after-party. The event was thrown by the CAA talent agency in honor of the show’s host Jason Sudeikis and the party list included a-listers like Cameraon Diaz, Chace Crawford, comedian-actor Aziz Ansari, “Captain America” cutey Chris Evan, MTV Generation Award winner Reese Witherspoon and “Harry Potter” actress Emma Watson. Their formal appearance at the Sudeikis party ended close to a month of speculation about the pair, who’d recently been spotted dining at the Sunset Tower Hotel.Prior to the MTV shindig, Theroux was introduced to Aniston’s close pals Chelsea Handler and Courteney Cox during a small get-together she threw over the Memorial Day weekend. Friends acknowledge that Theroux seems “edgier” than the other men who’ve been linked romantically to Aniston, but sources are saying that she’s smitten. The party also quashed reports that Aniston and Cox had been fighting. “They all had a great time and enjoyed Justin’s company,” one insider said.Up until a few weeks ago, Aniston’s rep was denying reports that the two were an item. But sources say that Theroux was all over Aniston during the after-party. Spectators witnessed some very public canoodling, that made it apparent the two were hot for each other.While Jennifer Aniston may have been keeping her new flame a secret from the public, Justin Theroux, 39, may be keeping mum about what’s going on with his long-time girlfriend, stylist Heidi Bivens. The two have been dating since 2005 and were most recently photographed together last February while attending various Fashion Week events in the Big Apple. Those in the know are claiming that Justin told his “secret girlfriend” Bivens that he and Aniston are nothing more than friends.Aniston’s had several other high-profile romances after her much-publicized divorce from actor Brad Pitt. Former beaus included singer-songwriter John Mayer and actor Vince Vaughn.
