Serena Williams has been single for some time, but with her best friend Caroline Wozniacki around, she feels more secure than ever in her singledom! The world number 1 is constantly celebrating her single life with the Danish tennis player. Now that Eugenie Bouchard has changed management to Serena’s, maybe she will also join in on the girl time!

Serena Williams posted a picture of her and Caroline Wozniacki on Instagram. These girls certainly know how to work hard and play hard!

 We should be sleeping but we are playing around. #iptl #breakthecode #mybff

Who needs boyfriends when you have a BFF!

Caroline Wozniacki and Serena Williams has a relationship that can make Maria Sharapova and Grigor Dimitrov jealous. This Thanksgiving, the world number 1 and the Danish player made a new best friend Thanksgiving tradition in Miami, strengthening the bonds of their friendship as well as stuffing themselves right before they start training for the Australian Open 2015.

Ever since her super public breakup with the Irish golfer Rory McIlroy, Caroline Wozniacki has found refuge in the world number 1 who also happened to be her best friend. Serena and Caroline has faced off in many Grand Slam tournaments, but all that competition has made them even better friends.

Maybe Eugenie Bouchard will join in on the girls-only festivities! She recently left her old management to sign with WME/IMG. Not only that, she will also be managed by Serena’s agent. Since the Canadian is also single, they will be able to spend some quality single gals’ time together.
