CELEBRITY FRIDAY: Grigor Dimitrov and Maria Sharapova Split Up

Tennis supercouple Maria Sharapova and Grigor Dimitrov have broken up, more than two years after they publicly acknowledged they were a couple in May 2013 (although many people believe they started seeing each other well before that date.) Dimitrov, who is now ranked #16 but has been in something of a slump for most of 2015, gave a press conference to confirm the break-up after multiple reports said that Sharapova had gone on vacation without him to Montenegro after being beaten by Serena Williams for the 17th time in a row in the Wimbledon semifinals earlier this month. Sharapova, 28, is back up to World #2 in the WTA rankings and was in the 2015 Australian Open final.

The 24-year-old 6-foot-2 175-pound Bulgarian is considered one of the best-looking men on the ATP tour, although he was cryptically described by Serena as a "guy with a black heart." Somehow, I don't think it's his heart that has made him so popular! Maybe he should share notes with Radek Stepanek.
