Ana Ivanovic has been enjoying a summer vacation in Mallorca, Spain for the last two weeks. The rumor is that she wants to invest in some real estate on the island. Oh and her tour guide for the trip? None other than Rafa Nadal. Me thinks something is going on between these two. Rafa gave Ms. Ivanovic a ride on his private plane after Indian Wells and now this. And I know Rafa has a girlfriend, but what man can resist Ana?
