It's the surprise hit of the summer.

And director Todd Phillips says audiences should prepare to get hungover again: A sequel to The Hangover has been confirmed.

“We were thinking of sequel ideas when we were shooting, which sounds cocky, but we were doing it more because it was just fun to talk about ideas while hanging out on the set,” Phillips told MTV. “Two weeks ago I was saying, ‘let’s see how it works out.’ Now that the movie has really connected, it’s something we’re doing for sure.”
