London: Caroline Wozniacki made sure Serena Williams was the butt of her jokes during her exhibition match against Maria Sharapova, by using towels to impersonate the ample curves of her American pal.
The 22-year-old Dane and Sharapova were in Brazil to promote the 2016 Olympic Games, but found time to lark around during the two-set contest, the Metro.co.uk reported.
The joke was not lost on Williams, who defeated Wozniacki in five of their six matches this year including quarter-finals at London Olympics.
She tweeted: `Do they make Brazilian bikinis for, um, well, me?`.
I was down 2-1 in the third it was really tight and it was really tough.
