Fun-loving Caroline Wozniacki made Serena Williams the butt of her joke at an exhibition match in Sao Paulo.
Wozniacki took on Maria Sharapova in front of a crowd that included boyfriend Rory McIlroy.
The Dane lost the match 6-2 7-6, and didn't seem to be taking things too seriously as she padded the, er, top and bottom of her outfit to give herself a curvier look.
The likeness to Serena, you'll surely agree, is uncanny.
Tennis impersonations are usually the preserve of Novak Djokovic - the madcap Serb has taken off big rivals Rafael Nadal and Roger Federer, as well as women's stars Williams and Sharapova.
Serena can afford to laugh off the light-hearted joshing - she has won five of her six matches against Wozniacki, including an Olympic quarter-final at Wimbledon this year.
Watch her hilarious routine.
