Novak Djokovic is known as the unofficial clown on the tennis circuit. From mimicking Sharapova to Nadal, he's known for his antics on and off the court.
Recently, Djokovic pulled another one of his comical stunts when he sang a rather off-key rendition of Call Me Maybe with US Olympic swim star Missy Franklin during a pre-tournament event for children at Arthur Ashe Stadium.
According to this Times of India report, Djokovic who got a standing ovation for his performance, had a good time. He said, "I enjoyed it. I tried even though my singing and dancing isn't that great It was exceptional fun. It was quite interesting. I haven't done much of that in my career."
But it seems the catchy song has got stuck in Djoko's head as well who also said, "I can't get the song out of my head. It's a very catchy song," Djokovic said. "Here's my number, so call me maybe."
