When it comes to celebrity bums the most desired derrieres are usually awarded to Pippa Middleton or Kim Kardashian but not by Nicola Roberts' standards…
The Girls Aloud star who is working closely with Rihanna in her new Sky Living fashion show, Styled To Rock told Look magazine not even RiRi's curvaceous bum does it for her.
Instead, she'd like to channel band mate's Kimberley Walsh's behind.
Nicola said: "I'm obsessed with her bum. It's a real issue. I was poking it. It's so soft and spongey. I'd love to swap bodies with her."
While on the subject of Girls Aloud Nicola kept the group's reunion plans closely guarded only revealing that it will be 'really fun'.
Oh the tease… but one thing the red head was willing to share was what it was really like to work with Rihanna.
She fessed up saying: "[Rihanna] couldn't have been more lovely, she's a real laugh. We all hit it off and had so much fun."
RiRi is the Executive Producer of the show while Nicola Roberts acts as the main host who works alongside Rihanna's stylist Lysa Cooper and Henry Holland to find one designer worthy of creating a look for the Bajan songstress.
