Kristen Bell: Monkey Madness at 'Hangover Part II' Premiere!

Kristen Bell kisses Crystal the monkey at the premiere of The Hangover Part II on Thursday (May 19) at Grauman’s Chinese Theatre in Los Angeles.

The 30-year-old actress paired her J. Mendel dress with Brian Atwood shoes and posed with one of the film’s stars, Crystal, who stole the show when she arrived in a pink dress and pearl necklace!

Also pictured on the Axe Excite-sponsored carpet: Kristen‘s fiance Dax Shepard, Robert Downey Jr., and the Hangover gang Bradley Cooper, Ed Helms, Zach Galifianakis, Justin Bartha, and Ken Jeong.

The crew then headed over to the Thai-themed after party, where they toasted the film’s premiere with Tabasco Bloody Mary-inspired cocktails.

FYI: Dax is wearing the Diesel Zatiny 8Y3 jeans.
