Serena Williams, Novak Djokovic dance at Wimbledon Champions' Ball

LONDON (AP) — 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" that starred John Travolta.

There used to be a formal ball held each year at the end of the tournament, and the men's and women's singles champions would dance there — but the musical part of the proceedings was discarded decades ago.

Djokovic called it a "tradition that was a bit forgotten," and said he suggested to Williams and the chairman of the All England Club, Philip Brook, that they bring the dancing back.
