P. Diddy stunned by party boy Jonah

Rapper P. Diddy was surprised at how hard his 'Get Him to the Greek' co-star Jonah Hill could party during a night out in Las Vegas.

P. Diddy was "shocked" at how hard actor Jonah Hill can party.

The rapper, who appears alongside Jonah in new comedy film 'Get Him to the Greek', invited the comic star and his friends to join him on a night out in Las Vegas, and Jonah was determined to have a good time.

The 'Superbad' star said in an interview with Filmbeat: "The weekend before we started shooting he took me and my friends from high school and university plus him and his friends there (Las Vegas) to kind of party and hang out.

"It was pretty crazy let me tell you. I have to be honest, I think he was really shocked by me and my friends because usually I'm just this boring guy."

The 26-year-old actor - who also stars in the movie with Russell Brand - usually prefers staying in to a night of clubbing, but did his best to impress the 'Bad Boy' hip-hop star.

He added: "Normally most nights I'm the guy who likes to just chill with my girlfriend, my buddies or my family and watch movies, and just hang out and talk or whatever.

"However, a couple of times a year we like to get together and really let loose and I think he was really surprised me and my friends. I was awesome."
