16. Caroline Wozniacki
Recently put back on the market after being engaged to professional golfer Rory McElroy, Caroline Wozniacki has bounced back to the form that saw her dominated women’s tennis from 2008-2011, and appeared to have been lost during the years she was with Milroy. Wozniacki has climbed back up to a number-one ranking, as well as completing the 2014 New York City Marathon. It is safe to say she probably won’t be looking to jump back into dating anytime soon.
