Serena Williams made out with Drake, putting her Grand Slam dreams at risk. Seeing how the world number 1 and her boyfriend-slash-coach Patrick Mouratoglou have been linked together for years, this sudden turn in the relationship may jeopardize her US Open 2015 dreams.

According to TMZ, “Here it is ... proof Drake and Serena Williams are officially a thing -- making out at a fancy Cincinnati restaurant Sunday night… Hours after Serena dominated and won the WTA tournament in Cinci -- with Drake in the crowd -- the two hit up the uber-fancy Sotto restaurant in downtown for some hoity-toity Italian food.”

This was after Serena Williams wrote on her Instagram that she and her rumored boyfriend Patrick Mouratoglou make a “dream team”. With US Open 2015 just a little more than a week away, the world number one has been steadily working towards the Grand Slam with her coach.

Not only has Serena won 21 Grand Slams, she is looking to complete a career slam this season by clinching the last remaining tournament - the US Open 2015. Not only is she a two-time defending champion, Serena thankfully lacks a real rival that threatens the Grand Slam.

This isn’t the first time that Serena Williams showed off her partnership with Patrick Mouratoglou on Instagram. But it looks like her fling with Drake may put things on the line.

In fact, the world number 1 was seen kissing Drake at Wimbledon. Until now, there has been no update on their relationship.

The world number 1 certainly didn’t deny that she tremendously benefited from her relationship with Patrick Mouratoglou. According to CNN, “Their trophy tally since teaming up includes a Wimbledon title, an Olympic gold medal, three U.S. Open titles, a Roland Garros title and an Australian crown, lifting her back up to the pinnacle of the women's game.”

Do you think Serena and Drake are a thing?
