Jade Ewen has admitted she thinks the Sugababes are "pretty much done".
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.
