*Serena Williams’ body became the focus of a mid-game prank by tennis player, Caroline Wozniacki, who stuffed both her chest and shorts with padding and pranced out onto the court mid-game to imitate her friend Serena Williams. [Scroll down to watch.]

Williams was not in attendance at the exhibition match this past weekend in Sao Paolo.

Reactions to this joke have been mixed. Yahoo Sports called the impression, “hilarious” and noted, “The likeness to Serena, you’ll surely agree, is uncanny.”

On Tumblr, bloggers weren’t so happy about it. One blogger adding: “…this isn’t “harmless fun” as one article described it. its racist. out and outright racism. mocking and making fun of the bodies of black women for a laugh? real funny, stupid white girl. real real funny.”

Another blogger pointed out: “So a white woman can do something like this, but Serena Williams can’t crip walk to celebrate a victory? Wozniacki stuffed her bra and underwear so that she could appear like Serena. It may have been done in “jest,” but I love how people can can turn a black woman’s body and sexuality into a caricature. However, we should not have the autonomy to celebrate any successes of our own.”

Caroline went on to lose to her opponent, Maria Sharapova. Watch her prank below.
