Watch: Novak Djokovic dancing to 'Gangnam Style' at US Open will make your day!

Five years since he first danced at the US Open, Novak Djokovic turned the Arthur Ashe stadium into a dancing floor yet again on Wednesday. 

After winning second round of US Open against Andreas Haider-Maurer, Novak Djokovic joined his superfan Cameron Hughes to do a 'Gangnam Style' impromptu dance on court.

In 2011, Cameron Hughes had showed off some moves at one of Djokovic's matches. Following his lead, Djokovic too performed a few steps on court. Later in the hallway to changing room the two met and the Djoker got a dancing lesson from Hughes.

Looks like the lessons improved World number one's dancing skills because this time they danced to Psy's 'Gangnam Style'.

The two waved the 'I love New York' T-shirts in the air trying to imitate the famous moves from 'Gangnam Style'.

Once done performing, Hughes once again made Djokovic wear one of his New York t-shirts.

"I'm glad that he came down to the court," Djokovic told ESPN. "It was not planned. I'm happy for him. He's a true entertainer. I know him for definitely five years. Each year I see him in one of my matches, dancing, taking down the layers of [his] T-shirts."
