Caroline Wozniacki has endured something of an up-and-down time during the last two years.
The former world number one fell to 10th in the rankings and failed to make the quarter finals of any of the Grand Slams in 2012.
She was even forced to deny her relationship with golf superstar Rory McIlroy was causing her drop in form.
But thankfully the stunning 22-year-old Danish star has managed to keep a sparkle in her eyes and her sense of humour, as witnessed by her display during an exhibition match with Maria Sharapova at the weekend:
Some tennis players are known for having a laugh, particularly Novak Djokovic. He has made a lot of fans for his impersonations of other stars.
We're not quite sure how Serena - a friend of the talented Dane - will respond to Wozniacki's towel-enhanced boobs and bum.
But that hasn't stopped some on social media from claiming the impersonation was racist.
On Tumblr one person wrote "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."
Executive director of the Australian Multicultural Foundation, Hass Dellal, says while Wozniacki likely didn't intend her actions to be racist they could be interpreted as such.
"It's quite inappropriate to be mocking or making jest of people's physical shape or image, especially when it's such an issue with young people today," he said.
What a load of nonsense. As any sports fan will tell you it's making fun of Serena because she's got big boobs and a big bum - nothing to do with her colour.Some people need to get out a bit more!
