Katy Perry offers to be One Direction star Niall Horan's 'Mrs Robinson' after snog at MTV VMAs

Niall Horan leans in for a kiss with Katy Perry

Taking home three MTV Video Music Awards last night clearly wasn't enough for Niall Horan - he nabbed a cheeky kiss from Katy Perry after she handed One Direction their Best Pop Video gong.

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?
