Speculation started after CNBC's Darren Rovell tweeted that "the two were seen cuddling up" during a U2 concert at the Rose Bowl.
Later Sharapova was spotted holding hands with her Serbian boyfriend (who was born in Slovenia), something which she has never done in public before. Huge PR boost for Vujacic!
Now that Sashapova has taken over the role from Klamar (Khloe Kardashian + LA Lakers Lamar Odom), most likely we'll see them often in gossip columns from now on.
