Let's hear it for the Girls (Aloud).

Kimberley Walsh sparkles as the March cover star of Cosmopolitan magazine, where she opens up about marriage, babies and the girl group the rocketed her to stardom.

She dismisses rumours about the girl band breaking up, telling Cosmo: "No way [it's not over]. I don't think we'll ever officially break up, to be honest. It'll be more a case of having breaks to go out and do little things we want to do, then coming back again. We'll definitely tour again. We're a live act; that's where we come into our own. Who knows - we might even have babies on board next time!"

Walsh also talks about marrying her boyfriend of seven years, Justin Scott, and how she'll definitely be waiting for him to pop the question - but not just yet.

The singer, photographed by James White for the cover and accompanying spread, flaunts her curves in figure-hugging and leg-revealing looks, and also shows off those amazing voluminous tresses.

Marriage and babies aren't the only things on her mind - Walsh also talks to the mag about her bestie, Cheryl Cole.

"Cheryl getting ill [with malaria in July]... was the toughest time for everybody close to her... It was terrifying, awful and bizarre... When I first saw her after she'd been ill, it was so emotional. I hugged her and I didn't really want to let her go. I was like, 'Sorry, I'm going to have to squeeze you for an hour.' I was so glad to see she was there in front of me, well. We had a good cry together."

"I do feel a little bit protective [of Cheryl]," Walsh continues. "I don't like the fact she's so trapped sometimes, trying to go out and about. There's not a great deal you can do about it but it frustrates me. Everyone deserves a little bit of freedom and she doesn't even have that."

Even though she's living the high life of a celebrity, home is still where her heart is - even if she no longer has a bedroom. "I love going back home," she tells Cosmo. "It's so comforting... all the responsibility is shifted off me for a while and my mum looks after me again. I've been booted out [of my bedroom]. My little sister took that over the minute I went. I've just been demoted to the box room. Sometimes I share with my sister, though, in my old room. Because there are four of us, when we're all home it's just grab a bed and hang on to it. But I wouldn't have it any other way!"
