Kimberley Walsh has admitted that she doesn't think Girls Aloud will perform together again.

Appearing on This Morning to discuss fundraising for breast cancer research in the name of former bandmate Sarah Harding who died of the disease last year, Walsh shut down talk of a musical reunion.

She told Dermot O'Leary: "I just feel for all of us, it would just be too painful.

"We’re so grateful that we had the time that we did and that we can find a way of doing something positive. But I don’t think it’s going to be something that we’ll do.”

Walsh did stress that the four remaining members of the group will continue to fundraise and appear publicly together: “We were all together, we did a gala for Sarah last weekend and we were all together, and lots of our GA [Girls Aloud] family were there and it just felt really special to have that night."

The pop star and presenter also revealed that Girls Aloud's debut album Sound of the Underground is being re-released with the proceeds going to charity: “We’ve got our Sound of The Underground re-release and all the money’s going to go to breast cancer research and the hospital that looked after Sarah, so that’s been a really good way, I think, of us finding something positive and a way to channel that.”

This year also marks 20 years since the formation of Girls Aloud on Popstars: The Rivals where Walsh, Harding, Cheryl Tweedy, Nicola Roberts and Nadine Coyle where selected for the group from thousands of applicants.

They went on to become the UK's biggest selling girl group of the 21st Century, selling over 4 million albums in Britain. Girls Aloud last performed together in March 2013 and announced their split on the night of their final concert.

Kimberley Walsh was unmasked as Oddsocks on The Masked Dancer over the weekend. Talking about appearing on the ITV reality show, Walsh said the hardest part was keeping it a secret from her family.

"My kids and my nephews are obsessed with the show and do Masked Dancer competitions every weekend so I wanted to do it for them," Walsh said.

"It’s the hardest thing ever [to keep it a secret]! I’m so close to my family, I feel like I have been avoiding them for weeks."

This Morning airs weekdays from 10am on ITV and ITV Hub.
