Katy Perry Tweets the 1D singer following a quick smooch at the LA ceremony
As his band mates left the stage, the 18-year-old Irish star turned back to Katy and leaned in for a quick snog.
Flirty Niall later Tweeted the US star a picture of the kiss, writing: ‘looks like its official … me and you‘.
Katy, 27, clearly enjoyed the encounter just as much as Niall, as she re-Tweeted his snap to her followers and added her own flirty comment.
‘I’ll be your Mrs. Robinson…,’ wrote Katy.
Maybe Niall has been taking tips from cougar-loving band mate Harry Styles?
