Word is that Maria Sharapova and Grigor Dimitrov have ended their off-court relationship. This mixed doubles pairing of two extraordinarily good-looking people began in late 2012 after the former's engagement to basketballer Sasha Vujacic had ended. ESPN sports business reporter Darren Rovell claims that he has it on good authority that, as love goes, the tandem splits sets.

Dimitrov shared the news with local press, but Sharapova hasn't spoken publicly to the breakup. The WTA Tour's No. 2 star took to a dance-off set to Beyonce's "Crazy in Love" with her favorite hair-stylist pal this week.

Meanwhile, Dimitrov himself ventured onto a clay court and hit a remarkable tweener in practice, pairing the video with a vague caption, "Dream big, be unrealistic."

Dimitrov announced that he was ending his coaching relationship with Roger Rasheed after his Wimbledon campaign ended in straight sets to eventual semifinalist Richard Gasquet. The 24-year-old is currently ranked No. 16 on the ATP World Tour but has slumped this season, doing so less dramatically than have the likes of Rafael Nadal and Eugenie Bouchard.

If Dimitrov's Instagram caption holds up, who knows what dreams may come?
