They're taking over the cinemas with their movie this weekend so it's no surprise that One Direction heartthrobs Harry Styles and Niall Horan are making an appearance on A League of Their Own this evening. They made a fair few headlines while filming this one, with Niall's backside making the gossip columns, so we're guessing you should prepare yourself for the usual antics and then some. If you've got teenage girls in the house there's no escaping it really.
