It was more monkey business than show business when Crystal the Monkey hit the red carpet at last week's "Hangover Part II" premiere in Los Angeles.
Dressed in her own custom gown, naturally, Crystal clawed and climbed up on many of her human costars, including Kristen Bell. This isn't the first time stars have had to share the spotlight with their animal counterparts. Check out of hilarious gallery of celebrities and animals ... together!
