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."
