We all wondered what was going on back in April when Bradley Cooper was pictured strutting about a movie set with the tightest curls since Justin Timberlake in his N*Sync days.

And now we know - it's for his new role in American Hustle. And today, we get the first look at the perm in action - and it's amazing.

The film stars Jennifer Lawrence too, and let's just say that her first film with Bradley since the Oscar winning film Silver Linings Playbook, and let's just say it's very different.

Jen strips off to her underwear in the film, set in the seventies, and she looks really, really hot. It must be all those fur coats.

She co-stars with Amy Adams , who ALSO takes off all her clothes - she plays Christian Bale's mistress, while Jen's her love rival - his wife.

The movie's already said to be an Oscar contender - it's packed with A-Listers too. Jeremy Renner , Jack Houston, Robert De Niro and comedian Louis C.K are all in there too. It's based on Jersey gangsters and crooked FBI agents in the 70s and 80s, which means it'll be wall to wall polyester suits and big hair.

We can't wait, but we'll have to, as it's not in cinemas until December.
