The singers spur each other on in the gym

Kimberley Walsh has found a gym buddy in her Girls Aloud band mate Cheryl Cole.

Kimberley, 30, and Cheryl, 28, often exercise together in order to perfect their super-toned figures.

Cheryl and I [work out],’ says Kimberley.

‘She’s a great work out partner ‘cos she’s not afraid of getting stuck in, and we’re good mates so we don’t care what we look like.

‘She spurs me on.’

Kimberley, who currently stars as Princess Fiona in West End musical Shrek, says she’s confident with her body and has learned to embrace her womanly curves.

But she admits it’s hard not to feel jealous of best friend Chezza, who’s naturally very slim. 

‘She’s got an amazing body!’ Kimberley tells Celebs On Sunday.

‘She’s so lucky, she’s got great genes. It’s not fair.

‘She’s always had great natural muscle definition, so for her it’s just maintenance, while I’ve had to work harder at it.’
