However fitting a Charlie Sheen cameo may seem, Cooper assured us the embattled actor will not be in the movie.
Nor will the former commander in chief.
"Bill Clinton, we saw him give a speech in Bangkok," Cooper told us last night at the Hollywood premiere of his new flick Limitless. "Me and Zachie [Galifianakis] and Todd [Phillips]...were honored enough to have dinner with him."
And what about a third Hangover?
"I mean, I would do anything with Todd and those guys," Cooper said. "If it was a great script, of course! And I love Phil. I love the character so much."
Hangover 3D, anyone?
