KATY PERRY - GYM CLASS HEROES: WE'LL NEVER WORK WITH KATY PERRY

GYM CLASS HEROES: WE'LL NEVER WORK WITH KATY PERRY

Despite Katy Perry topping the charts on both sides of the Atlantic, Gym Class Heroes' Travis McCoy doesn't plan to collaborate with his girlfriend.

Perry's I Kissed A Girl was number one in the UK for five weeks while the track - the 1,000th number one of the rock era in the US - held the top spot on the Billboard Hot 100 for seven weeks.

And with Gym Class Heroes' single Cookie Jar likely to dent the UK top ten this week, a collaboration between Perry and her boyfriend McCoy would seem a sensible decision.

But according to drummer Matt McGinley, the One of the Boys singer won't be joining the ranks of Gym Class Heroes collaborators - which includes Estelle, Kelly Rowland, Busta Rhymes and Fall Out Boy's Patrick Stump.

"More than it's my decision, I know it's something that Travis has said will never, ever happen!" he told inthenews.co.uk.

"It's not even a plausible option, he just won't do it."

Gym Class Heroes' new album The Quilt, featuring hit single Cookie Jar, is out now.
