The original line-up of pop group Sugababes have reunited under a new name.

The founding trio - Mutya Buena, Keisha Buchanan and Siobhan Donaghy - have been inactive since they disbanded in 2001, with other singers stepping into the band.

However, they have confirmed today (July 20) that they are reuniting and are working on new music under the name Mutya Keisha Siobhan. Siobhan Donaghy tweeted: "I'm excited to announce I'm back working with my original 90's girls."

The group meanwhile have already given their first interview since their reunion, with Keisha Buchanan admitting to Popjustice that they nearly got back together in 2009. She said:

"Well, back in 2009 I was contacted by the girls through my lawyer, and they were kind of like, 'Do you want to meet up?'. We all met up. I'd only been out of the band for three months and I'd just had enough of girlbands. I'd had enough of the WHOLE THING… Anyway, basically, they contacted me and we sat together and I actually really wanted to see the girls. Me meeting up with them was more about me wanting to see them than actually thinking about getting the band back together. Because like I say it was only three months after I'd left the Sugababes. So we decided not to do it. And then last year, in 2011, we were contacted by a producer. He put it to us: He said, 'Let's record a few tracks and then see'. And we did. And we loved it."
