Singer Kimberley Walsh thinks she looks too old to front a beauty campaign.

The 28-year-old Girls Aloud member - who is currently the face of British high street fashion chain New Look - claims she is already showing too many signs of ageing to be the perfect poster girl for anything that relied on her face.

“I’m always being told I should do a lipstick ad because of my huge mouth. But I think my skin might be too old for a beauty campaign. I’m 28 now. The wrinkles are starting to show!”

The singer also admitted she struggles to maintain a healthy diet regime, despite putting on weight more easily than her bandmates:

“I’m like any other normal girl, I have ups and downs; I can focus and be healthy for a few weeks and then I’ll have a bad week. If I ate what the rest of the girls ate I’d be three times the size, but at the same time, I’m not vain enough to starve myself. I’d much rather be content in my life and a normal size. I’m a 10 on top and a 12 below. I think it’s quite good for young girls that in the band we’ve all got different figures.”
