On Thursday May 19th, the Wolfpack was together again for the premiere of The Hangover 2 at Grauman's Chinese Theatre in Los Angeles, California.

First to walk the red carpet was Crystal the capuchin monkey, who caught a lift on her trainers shoulder and was outfitted in a pink Deb Scott couture gown and a lovely string of pearls.

Although it seemed like Crystal had stolen the spotlight at the premiere, as she was greeted by fans screaming "Oh my God! Look! Too cute!," some of the other Hangover 2 stars received the same warm welcome. Bradley Cooper had fans screaming as he ran up and down Hollywood Boulevard.

Actually the fans screamed for all the stars that walked the red carpet in front of Hollywood's most famous theatre. However, much to their disappointment, the stars didn't have any time to mingle with the fans because the premiere was running late and the actors were rushed into the theatre.

Ken Jeong and his wife Tran Jeong were all smiles as they walked the carpet together.
