Original members of the girl group Siobhan Donaghy, Mutya Buena and Keisha Buchanan are thought to be reuniting

The Sugababes may have had more dramatic exits, replacements, and in-house fighting than an episode of EastEnders, but it seems that the three founding members of the famous girl group could be planning a long-awaited comeback.

According to reports, Sugababes originals Keisha Buchanan, Mutya Buena and Siobhan Donaghy, who have all now left the group's forever changing line-up, have secretly reunited and have been in the studio recording a new album.

The trio only managed to record one album together before Siobhan decided to call it quits in 2001, amid rumours of constantly bickering within the girl band.

She was quickly replaced by Heidi Range, but peace was not too last and Mutya exited the band in 2005, which left Keisha as the only remaining original member in the Sugababes until she was kicked out of the band in 2009.

Rumours of a reunion have been rife after Mutya won the right to use the name Sugababes on a limited number of products early last year.

Keisha appeared to recently let slip to fans on Twitter that she was penning a new album with her former band members by writing: "Hanging out in the studio with @professorgreen and two lovely ladies with bags of talent :-p lol."

Although the newly reunited pop group band are yet to decide on a new name, they are reportedly in negotiations with three different labels.
