Katy Perry is "desperate" to have kids with husband Russell Brand.
Katy, who recently dyed her hair pink, has apparently asked Russell if he'd take a career break so the pair can start a family.
"Katy's desperate to have babies," the Daily Star report a source saying.
"But Russell's terrified what would happen to his mind if he stopped working."
But for now the babies will have to wait as Katy is currently on her US California Dreams tour, which has its second UK leg in October this year.
