Maria Sharapova, just back from the Olympics and prepping for the US Open, has launched a candy line, Sugarpova. But she tells us she isn’t planning a wedding — yet. The tennis star, who’s engaged to basketball player Sasha Vujacic, shot down reports she’ll wed in the fall. “Those are false rumors,” she told us at an event for her Hamptons magazine cover at the Sanctuary Hotel’s Haven Rooftop. “I don’t know where that came from. I think it started as a rumor, and everyone just went on with it.”
