Jennifer Aniston is dispelling rumors that she and beau Justin Theroux hooked up on the set of their new movie Wanderlust. The couple has been dogged by reports that Theroux cheated on his girlfriend of 14 years, Heidi Bivens, with Aniston while they were filming.

Jennifer cleared the air on Good Morning America, telling Lara Spencer, "Nothing happened on that movie . . . That's the easy rumor. But nothing happened, we were just friends. I've known Justin for a long time."

The pair have now been dating for about 11 months. Aniston refused to delve further into their personal life during the interview but admitted, "He's very cute."
