"It was funny!" he told MTV News on the red carpet of the film's NYC screening earlier this week. "We decided to hook up with the cast of 'Jersey Shore,' so we [also] linked up with Kim Kardashian and her sister Khloé. It was really fun."
The videos not only have the celebs jokingly promoting the film, but also show Bieber stretching his comedic muscle a bit and goofing off alongside the reality stars.
In the Pauly D promo, the "Jersey Shore" star makes this appeal to the camera: "I haven't been able to sleep. These thoughts keep running through my mind, that voice, that talent. This guy would kill it at the Shore," he says. "My hair won't even stand up anymore and I can't stop buying purple pants. I think I've got Bieber Fever. I've got to see this movie."
For the Situation's promo, he shares with the world his "Guide to Pimpin'." "How are you doing today, class? I'm here to tell about pimpin'. Justin Bieber's movie plus Valentine's Day, what does that equal to? Situation zone."
Bieber admitted at the screening that he thinks he can be funny. "I think I'm a funny kid, so I like to be funny," he smiled.
Perhaps as a testament to his love for comedy, Bieber also excitedly talked about the return of MTV's "Beavis & Butt-head." "I am [a fan]. I'm excited for the return," he said. "I like both of them. I just like the show in general."
Excited for his 3D movie? Let me know in the comments!
