Former Girls Aloud singer Kimberley Walsh has revealed her plans to have another baby.

Walsh, who will be appearing in the West End stage version of hit comedy film Elf later this month, said she and her fiance Justin Scott would love to give their son Bobby, 13 months, a sibling.

"It would be lovely for him to have a baby brother or sister," Walsh told Hello! magazine. "I come from a big family - with two sisters and a brother - and assume that he'd like the same.

"I used to be adamant about having four children - until I realised that it's not just about me. I adore being a mum and can't imagine not having more kids.

"Motherhood changes you. It makes you softer, more emotional; and you can't believe how obsessed you become by this little person in your life."

Walsh also opened up about her plans to marry Scott in a romantic ceremony next year.

"I'm very chilled about it. The venue is booked, I have the dress, so the important bits are taken care of. I'm getting very excited - but I'm no Bridezilla."

Despite still remaining in touch with most of her former bandmates, Walsh said she doesn't think there will ever be another Girls Aloud reunion.

"I think it's unlikely. I know the fans would love it and I don't wish to be negative, but I feel that as a band we had an amazing time and I'd like to leave it like that.

"We're lucky we had such a long career, and I'm fortunate to have made lifelong friendships in the process, but we're all in different places now. Maybe in years to come we might do a one-off show."
