The One Direction star - famed for his womanizing ways - attended a party at the house The Saturdays singer shares with husband Marvin Hunes, and after a few too many drinks, the 18-year-old heartthrob passed out in their pooch's bed.
Rochelle said: "I remember one time Harry fell asleep in my dog's bed! The boys were all at our house having a party and having a great time. Marvin BlackBerried me a photo and there was a body asleep in Tiger's bed. It was Harry! In there on his own, having a nap in the dog's bed, all curled up."
Rochelle has grown very fond of Harry and says he was thrilled to be a guest at her recent wedding to JLS singer Marvin - because there were so many female guests there.
She added to heat magazine: "I think he liked being at the wedding. You know what he's like - he gets linked to everyone, but he's never happier than when he's in a room full of women, so he liked the wedding."
