There have been rumors that Serena Williams may be juggling multiple men, but that might have been just that! The world number 1 was seen kissing Drake at Wimbledon, but there has been no follow through.

The fact that Drake was also seen flirting with Serena’s bestie Caroline Wozniacki, it’s unlikely that there was anything serious between the rapper and either of the ladies.

The world number 1 won’t deny that she has 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.”
