(Cover) - EN Star Style - Kimberley Walsh thinks its sickening that her Girls Aloud bandmates dont have to diet.

The 29-year-old is best known as one fifth of the successful British group along with fellow members Cheryl Cole, Nadine Coyle, Nicola Roberts and Sarah Harding. Noted for their raunchy music promos and toned bodies, Kimberley admits some members have to work harder than others to maintain a superstar figure.

The other girls in the band dont diet its sickening, but true, she told Closer magazine.

Kimberley has previously spoken of the extreme lengths she has had to undertake in order to preserve her svelte figure. Having followed intense workout sessions and adhered to health regimes in the past, Kimberley confesses that she often looks at her bandmates with envy due to their lack of body worries.

They are blessed with fast metabolisms but Im not. If I ate as much as Nicola [Roberts] Id be in trouble, she added. (C) Cover Media
