3. Niall Horan and Katy Perry
Katy and Niall's lovin' goes all the way back to when the boys were on the X Factor, and a couple of years later Mr Horan was even rumoured to have asked K-Pez to marry him! Sadly Katy confirmed they were just rumours, and the pair are only good pals (who enjoy a little public smooch every now and again, obvs.) Picture: Getty
