Gossip Girl star Blake Lively is sure to set tongues wagging with her saucy new movie.

The actress - who plays the very stylish Serena van der Woodsen in GG - gets to grips with the very different role of 'Young Pippa' in The Private Lives of Pippa Lee, about a teenager who runs away to live with her aunt Trish in New York.

The spanking arises from the fact that her aunt's live-in girlfriend is a dominatrix who specialises in photographing sadomasochistic sex acts.

Pippa is introduced to the world of S&M and persuaded to star in a home-made film - hence these kinky scenes!
