Mutya, Keisha and Siobhan - the original Sugababes line-up - will be back with a new album in 2017.
Siobhan Donaghy confirms they'll release a record next year - although she won't give an exact date.
The three girls reformed back in 2012 but the comeback stalled after they released single, Flatline.
The original Sugababes released their album One Touch in 2000, which featured singles Overload, before Donaghy quit.
Heidi Range then took her place, with Buena leaving in 2005 to be replaced by Amelle Berrabah. Buchanan became the only original in the band until 2009, when she left the band to be eventually replaced by Jade Ewen.
