'I Kissed A Girl' star Katy Perry's boyfriend has banned the singer from smooching women.

Gym Class Heroes' star Travis McCoy - who has been dating the brunette
beauty since 2005 - insists he should be the only person Katy kisses.
When asked which woman he would like to see his girlfriend kiss, he replied:
"Definitely none!"
However, Travis then seemed to have a change of heart and added: "Well,
maybe Elisabeth Shue. She was my first crush from the movie 'Adventures In
Babysitting'."
Travis revealed he loves being in a relationship with 23-year-old Katy, and
enjoys their morning cuddling sessions.
He said: "It's kind of silly, but I love it. And also just goofing around.
We kind of have our own language that only we understand - it just works."
The 27-year-old rocker also spoke about the promise ring he gave Katy, and
admitted it is his way of signifying his commitment to the singer.
He added to Us Weekly magazine: "I guess I'm kind old school - it was a
token of my affection and a way to show her that I wanted to take it to
another level. Not the next, next level, but a level above where we were
at."
