Former Sugababes member Mutya Buena has denied reports that the original line-up of the band are reforming.

Reports emerged last week that Keisha Buchanan, Siobhan Donaghy and Mutya Buena are set to head back into the studio to work new material.

The group are reportedly  managed by Felix Howard, who wrote the original line up's hit single 'Overload'.

However, Buena has told fans over Twitter that there is no truth in the claims: No track [with] Keisha or Professor G, he was around the studio. I'm just working on my stuff at the moment

Meanwhile, Sugababes star Jade Ewen has insisted that she has not quit the girl group.

The singer was forced to issue an official denial (September 21) after rumours circulated on Twitter over night that she had left the band.
