Simon Cowell

One Direction's record label boss Simon Cowell sent each band member a bottle of bubbly to celebrate winning three Moonmen at the MTV Video Music Awards, despite the boys being under the drinking age in the USA, according to MTV UK.

Cowell tweeted: "Congratulations 1D. I'm very proud of you. Celebrate!"

All in all, it was a great night for the boys. Niall Horan and Harry Styles each got a kiss from Katy Perry.

Niall later tweeted a pic of the smootch, writing: "@NiallOfficial: @katyperry looks like its official ... me and you."

Ms. Perry responded by tweeting: "I'll be your Mrs. Robinson..."

One Direction won awards for Best Pop Video, Most Share-Worthy Video and Best New Artist.
