They may be costars onscreen – but it looks like these guys are still feeling the love even after the cameras stop rolling.
During the recent Parisian premiere of I Love You Phillip Morris, Jim Carrey couldn’t help but plant a sweet one on Ewan McGregor. (The two play lovers in the flick.) And though he may be engaged to Katy Perry, Russell Brand was feeling warm toward his Forgetting Sarah Marshall costar at a Haitian earthquake benefit in L.A. on Tuesday. Even Josh Brolin, who played Sean Penn’s archrival in Milk, couldn’t suppress his affection for his former costar. How sweet!
