Pop star Katy Perry is still "hurting" over her split from rapper Travis McCoy - but insists she's "over it".

The I Kissed A Girl hitmaker broke up with the Gym Class Heroes frontman in December after weeks of arguments.

And while a bitter McCoy has turned to his online blog to air his feelings about his ex, Perry decided to address the failed romance at her show at Los Angeles' Hotel Cafe on Monday night - hinting it was McCoy who pushed her away.

She told the crowd, "It hurts right now. When you break up with someone you move on.

"You don't really want to move on... but you have to because they don't give you any choice. But I'm over it!"
