The American tennis star, who taunted the crowd after beating local favourite Destanee Aiava, has made good on her pledge to splash her Australian Open winnings on a luxury break.

After a back-and-forth with the Australian Open crowd, the American vowed to make the most of her Grand Slam paycheck.
