The lead actors' gorgeous looks, however, are overshadowed by Crystal the monkey's actions as she jumps here and there on the black carpet.
"The Hangover Part II" cast jetted to Los Angeles, California to premiere the movie at Grauman's Chinese Theater on Thursday, May 19. Four lead actors, Bradley Cooper, Zach Galifianakis, Ed Helms and Justin Bartha, as well as supporting actor Ken Jeong put on their suits when coming to the event.
Looking dapper in his brown ensemble, Cooper was goofing around with Mike Tyson, who has a cameo role in the upcoming film, on the black carpet. Robert Downey Jr. and Susan Downey made guest appearances at the special screening which was already star-studded with the presence of Kristen Bell, Jordin Sparks and Alyssa Milano among others.
Stealing the spotlight, however, was Crystal the monkey which is a new cast member of the comedy. She arrived in a glamorous dress, posing on the black carpet like a true celebrity. At other times, the fury animal jumped on the guests' shoulders including Bell's, messing the actress' sophisticated look as she pulled Bell's blonde hair.
A sequel to "The Hangover", "The Hangover Part II" follows Stu, Phil, Alan and Doug who travel to exotic Thailand for Stu's wedding. After the unforgettable bachelor party in Las Vegas, Stu is taking no chances and has opted for a safe, subdued pre-wedding brunch. However things go awry as they gang lose Teddy, Stu's future brother-in-law. The movie will open wide in the U.S. on May 26.
