Perry 'banned from kissing girls'

The boyfriend of 'I Kissed A Girl' singer Katy Perry has banned her from smooching with other women.

Gym Class Heroes star Travis McCoy told US Weekly that he should be the only one Perry puts her lips on.

However, he admitted that he might be swayed, saying: "Well, maybe Elisabeth Shue. She was my first crush from the movie Adventures In Babysitting."

Perry recently told the Daily Star that she has been too busy to enjoy a good night's sleep.

"Sleep is very foreign to me," she remarked.
