Bradley Cooper discusses working with a monkey

Bradley Cooper spoke very highly of one of his co-stars – a monkey.

The lucky monkey, called Crystal, stars alongside the sexy Mr Cooper in The Hangover 2.

“Crystal is great,” gushed Brad. “She actually plays a he in the movie but you’d never know. I worked with her before so this was our second time together which was pretty special.”

“The first time she didn’t have diapers on so sitting on my shoulder could be a problem but this time she had diapers so we had a great time.”

Lucky, lucky monkey.
