The Psy imposter who tricked the Cannes Film Festival with his copycat Gangnam Style

Imposter! A Psy impersonator duped organisers and celebrities at Cannes Film Festival. The look alike waved as he left the Hotel Martinez on Tuesday

A Psy impersonator duped organisers and celebrities at Cannes Film Festival.

A man posing as the Gangnam Style hitmaker managed to sneak into several A-list parties and other exclusive venues over the course of two days earlier this week until finally being discovered yesterday when the real Psy appeared on US talk show Live with Michael and Kelly, which is filmed in New York City.

The impersonator reportedly scammed free drinks and bottle service while lunching at the Torch Beach Club, a hotspot which has been frequented by Justin Timberlake and Mark Ronson during their time in Cannes, and was even surrounded by three security guards, according to the New York Post newspaper.

Later, the man partied at an A-list bash hosted by socialite Goga Ashkenazi at Château Garibondy, where the guest list included Trance actress Rosario Dawson and supermodel Karolina Kurkova.

While the fake Psy was enjoying the luxury on offer in Cannes, the real Gangnam Style star attended the Billboard Music Awards in Las Vegas, Nevada on Sunday and later jetted to New York City to film a TV appearance.

Acknowledging his trouble-making doppelganger, Psy wrote on Twitter: 'Seems like there's another ME at cannes...say Hi to him.'

Among the celebrities duped by the impostor were Skyfall actress Naomie Harris, who thought she had met Psy at a party thrown by Chopard on Tuesday, and tweeted a snap of them together.
