We already knew Wozniacki was in the issue, featured in a cover story about her friendship with world No. 1 Serena Williams.

The photo of Wozniacki was actually featured in the online version of the Vogue cover story that went live Saturday and details the well-known friendship between the two tennis stars. Their exploits have involved everything from taking in a Miami Heat game to owning New York City.

Wozniacki was the No. 4 seed at the BNP Paribas Open this past week, where she was upset in the third round by No. 31 Belinda Bencic.
