Photo:The original members of the Sugababes have registered the name 'Mutya Keisha Siobhan' ahead of their comeback later this year.
The trio, who made their pop debut in 2000 founded the name but is currently the property of their former record label, and still used by Amelle Berrebah, Heidi Range and Jade Ewen.
Mutya Buena currently owns all rights to stationary bearing the name 'Sugababes' after winning a court case in 2010.
Mutya Buena, Keisha Buchanon and Siobhan Donaghy signed a £1million deal with Polydor Records in April 2012 and have been working with MNEK, Asterix and Craze & Hoax on their first album as a three-piece since 'One Touch' in 2000. BRIT Award winner Emeli Sande has also revealed she has been writing tracks for the trio.
Siobhan Donaghy quit the girlband in 2001 to be replaced by Heidi Range. Mutya Buena left in 2005, having her place filled by Amelle Berrebah and Keisha Buchanon quit in 2009.
