Denis Carré, a Psy lookalike, duped hundreds of people with various appearances during the recent Cannes Film Festival and now he has struck again, attending the Monaco Grand Prix over the weekend while the real singer performed in Italy on the same day.

Among those duped by Denis Carré’s appearance at the racing event were Amanda Holden and David Hasselhoff, who both posted pictures of themselves with the lookalike on their Twitter pages.

However, Amanda Holden appeared unsure if she was actually posing with Psy in the shot, captioning the picture: “Not sure if this guy is kosher?! Rumors circulating he was a fake? What do YOU think?!”

David Hasselhoff seemed a bit more certain that he wasn’t with the real Gangnam Style musician, tweeting with a picture of himself and girlfriend Hayley Roberts with “Psy”: “Was that really PSY ? I think not!!”

Other stars to have been duped by Denis Carré included Skyfall actress Naomie Harris, who unwittingly posted a picture of herself on Twitter with who she thought was Psy.

Speaking recently about how he managed to convince so many people that he was the singer, Denis Carré credited the scam to an intricate web of tricks.

He told Channel 5 News: “The game was pretty well played – we prepared a lot with my manager and communication team on how we were going to do that.

“We had the bodyguards, we had the cars, we had event managers ready for it… just to have the illusion.”

The trick was revealed when the real Psy appeared on US talk show Live with Michael and Kelly, which is filmed in New York City, while his imposter was in Cannes.

Denis Carré is said to have 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.

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