Nude pictures, supposedly of Blake Lively, are circulating online although the Gossip Girl actress is claiming the photos are fake.

The pictures, which it is claimed show Blake Lively naked, are of a blonde girl posing with no clothes as she photographs herself in the mirror.

However, Lively’s spokesperson has denied that the nude pictures are the real deal, saying:

“The photos of Blake Lively which have just surfaced on various websites are 100 percent FAKE. Blake has never taken nude photos of herself.”

The Gossip Girl actress, who has just signed a deal with Chanel, is now threatening to take legal action.

According to Lively’s reps, the naked pictures have been photoshopped.

Blake Lively is rumoured to be dating Leonardo DiCaprio after the pair were first spotted together at the Cannes Film Festival.

Fuel was added to the fire when Lively and DiCaprio were seen looking romantic in Monte Carlo this weekend, as they checked out the Monaco Grand Prix.

Lively and DiCaprio were photographed walking hand in hand, eating dinner together and going into a hotel. On Sunday, the pair partiedy aboard Top Shop boss Sir Philip Green’s £32 million Benetti superyacht.

Inception star, DiCaprio only recently split from his long-term girlfriend Bar Refaeli but appears to have successfully moved on with Blake, who he first men when she auditioned for the role of Daisy Buchanan in Baz Luhrmann’s upcoming adaptation of The Great Gatsby.
