One Direction's Niall Horan has joked he hasn't washed his face since Katy Perry kissed him.
The boyband heartthrob puckered up with Katy at this year's MTV Video Music Awards (VMAs).
The 19-year-old has fond memories of the night, collecting three awards with bandmates Zayn Malik, Harry Styles, Liam Payne and Louis Tomlinson, along with the cheeky kiss.
"Katy Perry had lovely purple lipstick on and I still haven't washed it off to be fair!" he joked to Australian radio show hosts Kyle and Jackie O.
Despite enjoying some Twitter banter with the 27-year-old pop star afterwards, Niall says the band is careful about what they write online.
Zayn even closed his Twitter account for a short period in August, following negative comments on his page.
"We know not to overstep the mark online!" Niall explained. "It's common sense, you don't have to be a genius to figure it out."
One Direction are releasing their second album, Take Me Home, on November 12.
