The singer revealed that he has become friends with the South Korean popstar, who has topped charts all over the world with his viral hit.
"I do the 'Gangnam Style' better than Psy himself," Usher joked to Capital FM.
"We've hung out a little bit, man, we're friends. He's cool, man. He took me to a Korean club in New York City."
He added: "Oh my God, they really party hard. It was so cool to see what he's able to do in his world. With this dance craze it just introduces you to something different."
The 'Gangnam Style' has been attempted by many celebrities all over the world, with Australian X Factor judge and Spice Girl Melanie B recently performing the jig with Psy on stage.
