Mutya Buena, Keisha Buchanan and Siobhan Donaghy have confirmed plans to release a new album later this year and have posted the first picture of themselves as a reformed trio.
"Dear tweeters ive been trying my best to keep this one on the DL haha @mutyabuena @siobhandonaghy @mksofficial," Buchanan revealed.
"It's been killing us to keep it secret any longer! @keisha_buchanan @MutyaBuena," Donaghy added.
"@siobhandonaghy @keisha_buchanan I think we should tell the world. WE'RE BACK!!! @MKSofficial," said Buena.
The girl group also confirmed that they will release music under the name Mutya Keisha Siobhan, after registering the trademark for the name late last month.
The three-piece have explained that when they first reformed they had to work on their harmonies, having not performed together since they were 16 years old.
"The first time we sang in a room together and worked out our harmonies and sang them together was recording a song called 'Too In Love'," Siobhan told Popjustice.
Buchanan added: "It was the first time we'd sang together since we were 16 years old. To be honest with you it wasn't an instant thing. When we were younger we gelled straight away, but we had to learn to blend with each other again.
"It was so special to be excited about hearing our voices together, and being excited about our music. On my days off I'd go home and I'd listen to the tracks. I'd be like, 'I'm really enjoying this'. I just enjoyed our music."
Mutya Keisha Siobhan will officially release their new music in the near future.
