Serena Williams has showed Twitter fans she's ready for summer, posting a revealing new bikini pic.
The 30-year-old tennis star put her uber-toned butt on blast as she posed on the beach in a bright pink figure-hugging bikini set.
Serena added a cheeky joke caption to the pic, simply Tweeting the message: 'beach bum'. Within hours the pic had racked up over 50 retweets and 'favourites'.
Rumours are still swirling Bulgarian tennis player Grigor Dimitrov is the lucky guy getting his hands on Serena's rock hard cakes, with the pair spotted going out for cosy lunches in Paris last month.
Anyone else feel really, really sorry for Drake and Common right now?
