Sharapova called off her engagement to Sasha Vujacic at the end of last spring. This lead to the world wondering who she is dating at the moment, so now we might know.
However, while in Milan recent for an exhibition match Sharapova was spotted with Grigor Dimitrov.
In this video at 16:00 they happened to meet in Milan and seemed to be joking and laughing about the press being there.
p.s. A lot of news services are called Dimitrov the next Roger Federer, but I think its way too early to say such things!
