One Direction's singer Niall Horan joked that he has not washed his face since Katy Perry kissed him.

The young singer received a kiss on the lips from Katy at the recently concluded MTV Video Music Awards where the band collected three awards. Along with his band mates, Zayn Malik, Harry Styles, Liam Payne and Louis Tomlinson, Niall Horan said the awards' night is a memorable experience.

"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.

Niall says the band is careful about what they write online since whatever they post online gather immense attention from their fans and haters all over the world.

"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."

Niall Horan was linked to "X-Factor" judge Demi Lovato. Last month, Niall Horan made the fans crazy after he and rumored girlfriend Demi Lovato exchanged sweet tweets to each other.

Everyone is curios if the two are really going out as Niall Horan called Demi Lovato "honey" when the former greeted the latter on her birthday.

The 18-year-old singer tweeted a special birthday message, which caused chaos in the social networking site and "Nemi" couple was soon trending. The 1D singer initially denied that there is something going on between him and Demi and said that they are good pals.

However, the One Direction's singer was caught earlier cuddling with sexy Cover Drive singer Amanda Reifer.

The two also snap a picture together. Amanda was apparently thrilled to meet the 1D lad at her band's gig in Brighton on Monday. This may shocked many Nemi fans.

One Direction will be releasing their second album, Take Me Home, on November 12.
