Did Paul Rudd Reveal Jennifer Aniston’s Boyfriend?

The secret may have been trickling out over the past few days, but Paul Rudd didn't seem to know it when he say down to tape "Late Show" (Weeknights, 11:35 p.m. EST on CBS). So when David Letterman started poking and prodding him about the love life of his "Wanderlust" co-star Jennifer Aniston, he balked and hesitated at first.

"I think somebody in the film actually is a "friend" of hers," Letterman said. "Am I right about that? Maybe you can't say. Can you say?"

He pushed and pushed until finally, Rudd replied, "Jennifer Aniston is dating Justin Theroux." Theroux also stars in the film with Rudd and Aniston. The two have reportedly been romantically involved since May 2011.

"You heard it here first," Rudd said, which may not actually be true for many die-hard Aniston fans. She's been making the rounds herself in promotion of the film and has begun talking more openly about her relationship. Plus, Theroux was present when Aniston recently received her star on the Hollywood Walk of Fame.

Paul Rudd can be seen starring alongside outed lovers Jennifer Aniston and Justin Theroux in the comedy film "Wanderlust," in theaters February 24, 2012. David Letterman can be seen on "Late Show" weeknights at 11:35 p.m. EST on CBS.
