American tennis player Danielle Collins embraced the Australian Open boos after her latest win. But there's more to her heel turn than meets the eye.

Danielle Collins appeared to revel in playing the part of pantomime villain at the Australian Open on Thursday as she took down home favorite Destanee Aiava 7-6, 4-6, 6-2 in front of a raucous crowd.

Djokovic said he loved "everything" the American said while getting the last word on a hostile Australian Open crowd.
