After winning titles again on Wimbledon's grass, Novak Djokovic and Serena Williams showed they can cut a rug, too.

Reviving a bygone tradition, Djokovic and Williams busted a move at the Grand Slam tournament's annual champions' dinner, dancing together to "Night Fever," the Bee Gees' disco hit from the 1977 movie "Saturday Night Fever" starring John Travolta.

At a news conference at the All England Club on Monday, a day after beating Roger Federer for a third Wimbledon title, Djokovic says it was his idea.

Says Djokovic: "Serena is a great dancer."

As for the song choice at Sunday night's dinner, Djokovic says he originally had in mind "more of a waltz or something" but Williams, who won her sixth Wimbledon title Saturday, "wanted to move a little bit more."
