Girls Aloud's Kimberley Walsh admits Sarah Harding spends the most time preening herself.

When asked who checks themselves out the most, Kimberley told OK! magazine: "Oh, it's a tough one between Sarah and Nadine [Coyle]! I think Sarah perhaps a little more."

Kimberley also revealed she and close pals Nicola Roberts and Cheryl Cole tend to annoy the other girls with their tireless gossiping.

She laughed: "Probably me, Cheryl and Nicola [are the biggest gossips]. The other two look at us like were old women."

However, when it comes to making long-distance calls, Kimberley admitted that Nadine - who lives in Los Angeles where she runs an Irish pub - is constantly on the phone discussing new work opportunities.

The sexy star explained: "I guess because she knows a lot of people in LA now and needs to be connected more."

Kimberley wouldn't gossip quite as freely about her ten-year relationship with Justin Scott, however, and simply insisted their long-term love is able to withstand the pressures of her showbiz lifestyle.

She said: "We have a solid base and other outside factors don't really cause problems. I wouldn't listen [if someone tried to split us up]! But I'm older now and it's never really been an issue, even in the early days of the group it was never put to us."
