Jade Ewen has admitted she thinks the Sugababes are "pretty much done".
The singer is part of the band's latest incarnation which features no original members, but said she couldn't see herself going back into the studio with Amelle Berrabah and Heidi Range.
She told Digital Spy: "I don't even know if the band stuff is going to happen again, if I'm completely honest. I think Amelle wants to do her own solo stuff, Heidi is doing a Happy Days musical... I think we're pretty much done.
"I'm working on solo material at the moment actually. It's only come about in the past three weeks, so it's quite a new project. No-one's really seen me yet. I sang for Eurovision, I've been in a band, but I don't think anyone really knows what I'm about."
But despite feeling there won't be another Sugababes album, Jade said she'd love to reunite all six band members from previous line-ups for a tour.
She said: "I would love to do a giant tour of all the Sugababes, old line-up and new line-up. That would be awesome, it would sell out. That's easy for me to say though, I don't know how that would go down [with the other girls]. But I'm definitely up for it."
Original Sugababes Mutya Buena, Keisha Buchanan and Siobhan Donaghy are now performing together as MKS, while Jade, Amelle and Heidi have been on a break since releasing album Sweet 7 in 2011 although Amelle had claimed in May they were thinking of getting back into the recording studio in 2014.
