Danielle Collins, the American tennis star, once again faced a rowdy crowd as she took to the court for her third-round match against Madison Keys at the Australian Open.

Collins became public enemy No.1 in Melbourne when she gleefully wound up a raucous home crowd following her hard-fought win over local hope Aiava on Thursday. After winning, she cupped her hand to her ear and yelled “How about that?” before blowing kisses to the crowd and slapping her backside.
