One Direction's Irish heartthrob Niall Horan has admitted that he doesn't want to wash Katy Perry's kiss off his face.

The 'Teenage Dream' beauty congratulated Horan on his recent win at the MTV VMAs by giving him a purple lipstick-tinged peck on the lips, and he joked to Australian radio show hosts Kyle and Jackie O that he was so excited about it he hasn't washed since:

"Katy Perry had lovely purple lipstick on and I still haven't washed it off to be fair!"

He then opened up about both his and his boyband's relationship with social networking sites and spoke about the importance of keeping an audience in mind when writing public messages because not only do people look up to him, but they can also judge him on what he posts:

"We know not to overstep the mark online! It's common sense, you don't have to be a genius to figure it out."
