Katy Perry reportedly infuriated her management team after cancelling a U.K. TV appearance so she could spend time with new boyfriend Russell Brand.
The I Kissed A Girl singer was due to appear on Chris Moyles' Quiz Night on Tuesday (10Nov09) but her funnyman beau phoned the programme's host hours before filming to let him know the pop star was unavailable.
Panicked TV bosses were left scrambling to find a replacement, before eventually persuading Mamma Mia! actor Dominic Cooper to take Perry's place.
A source tells British newspaper The Sun, "Katy was due to be the star guest on Chris' show. But he got a call from Russell late the night before telling him Katy wouldn't be appearing as they wanted to spend the evening together.
"Chris was a bit annoyed but thinks Katy is hot as well - and if she was his girlfriend he would probably do the same!"
The publication alleges bosses at Perry's record label were furious after she was photographed going to a London restaurant with Brand while the TV recording took place.
