It's Harry Styles!
The One Direction superstar has been taking some time out of his super busy schedule to enjoy some relaxing down time in the pool. He's been Instagramming a few pics of his swimming lately, and he captioned this one “Swim sir.”
Maybe you guessed right because of the hint about his love life – rumors have been going around that Harry's dating 19-year-old model Cara Delevigne (though they've both denied it).
Congratulations to Wambie girls Sarah, Kate, and OneD for being the first three to correctly guess it!
