London: Katie Perry avers that Brit girls are the most dirtiest in bed.
And the pop starlet claims to know it all because fiance Russel Brand, 35, has shared all his sexcapades with her.
“My boyfriend has had a few!” the Daily Star quoted Katie, 25, as saying.
“Obviously I like to have a good f***ing time too. I’ve got that in me as well – the pure filth part,” she added.
