Niall Horan scored a smooch from Katy Perry
Meanwhile, Katy caused a frenzy up on stage (and in the social media world!) when she gave One Direction star Niall Horan a proper smacker of a kiss on the lips on stage! Cute Irish singer Niall then posted the picture on Twitter saying 'it's official... me and you' and Katy retweeted it, adding 'I'll be your Mrs. Robinson...'
Oo-er! Take that Harry Styles - Niall just saw your Caroline Flack and raised you a Katy Perry!
