MKS have revealed they would consider a collaboration with Girls Aloud.
Mutya Keisha Siobhan - who originally formed the Sugababes - went on to explain that they would only duet with Cheryl Cole and Co if it was for charity.
When asked if they would team up with the girls on the next Comic Relief single, Mutya told Popjustice: "Why not? I love Girls Aloud. I've always liked the girls."
Keisha Buchanan agreed: "That would be a good thing," while Siobhan added: "And we're so different that I actually think we'd complement each other."
Buchanan previously collaborated with Girls Aloud on a cover of Aerosmith's Walk This Way for Comic Relief in 2007 as part of the Sugababes line-up consisting of Heidi Range and Amelle Berrabah.
In other MKS news, the trio have told fans they can expect new music by the end of this year.
