Girls Aloud star Kimberley Walsh has revealed that competing on Strictly Come Dancing has given her a "bum lift".
The curvy singer has been dancing for around seven hours a day to prepare for her performances on the hit BBC1 show.
The 30-year-old, who finished joint second on the leaderboard at the weekend with Victoria Pendleton and Michael Vaughan, told Heat magazine that she was reaping the benefits of her rehearsals with professional dance partner Pasha Kovalev.
"My bum's lifted slightly (since I started training)," she said. "I can see some liftage going on. It could still be a little bit firmer."
Kimberley said her Girls Aloud bandmate, Nicola Roberts, was obsessed with her derriere.
The singer, who is set to embark on a 12-date Girls Aloud reunion tour, said: "It could still be a little bit firmer, although I don't think Nicola would like that. I think she likes the fact that it moves.
"That's what is so fascinating to her, because she has a nice little pert, firm bottom.
"Mine has a bit of movement, and I think that's why she's fascinated by it. She's like 'Touch it! Touch it! Look at it!'
"And I'm like 'Yeah, that's called wobbling. But if you like it, that's fine.'"
Kimberley added: "Do you know what? I'm actually quite fine with having a larger bottom. It's part of who I am."
