New York, Sep 3 (IANS): Serbian tennis star and World No.1 Novak Djokovic showed off his dance moves on court with a fan while celebrating his comfortable straight sets triumph over Austria's Andreas Haider-Maurer in the US Open men's singles second round.

The Serb took his time to find his rhythm against Haider-Maurer before shifting through the gears to claim a 6-4, 6-1, 6-2 win at the end of Day Three at the Flushing Meadows here on Wednesday, reports dailymail.com.

The top seed will now play Italian Andreas Seppi in round three, but Djokovic's post-match interview was hijacked as one fan jumped down from the stands to cajole him into showing some dance moves while music blared out around the arena.

The nine-time Grand Slam champion seemed only too happy to oblige as the pair performed a short 'gangnam style' jig, which ended with Djokovic high five-ing his partner and putting on an 'I love New York' t-shirt, handily supplied by the fan, who also had one himself.

'Gangnam' is a dance style popularised by South Korean pop star Psy.

“I'm glad that he came down to the court. It was not planned,” Djokovic said during his press conference after the match.

He insisted that he had seen the fan, whose routine seems to involve stripping down layers of t-shirts while dancing outrageously, at his matches for five years.

“He's a true entertainer. Each year I see him in one of my matches, dancing, taking down the layers of the t-shirts. But, you know, it never gets old,” he said.

After clinching his third Wimbledon title two months ago, Djokovic took to the stage with Serena Williams to become the first champions to dance officially since Bjorn Borg and Chris Evert in 1976.
