The trio will make their comeback under the name of Mutya Keisha Siobhan or MKS for short, with the first official picture of the girls being released today (20th July).
Keisha first addressed their reunion plans on Twitter, writing: "Dear tweeters ive been trying my best to keep this one on the DL haha @mutyabuena @siobhandonaghy @mksofficial."
Donaghy added then added: "It's been killing us to keep it secret any longer! @keisha_buchanan @MutyaBuena."
Beuna then announced: "@siobhandonaghy @keisha_buchanan I think we should tell the world. WE'RE BACK!!! @MKSofficial."
MKS are set to officially release new material in the near future, with Siobhan telling Popjustice: "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.
Buchanan said: "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."
