NEW YORK (AP) — Will Serena Williams dance at the U.S. Open? The Olympic singles champion isn't sure.

Williams caused a stir with her celebratory "crip walk" dance when she beat Maria Sharapova at the Olympics this month, but has nothing planned if she wins next month's Open. She says the first dance was impromptu. She adds: "I have to win seven matches, so we'll see."

The Wimbledon champ joined fellow tennis players Victoria Azarenka, the Bryan Brothers and James Blake at Thursday's annual Taste of Tennis, where top chefs provide culinary delights in an event for charity. Blake brought his infant daughter, who was cradled by Williams.

Williams says she's still on an Olympics high. She says she and sister Venus plan to be in Rio de Janeiro for the next Summer Games.
