The original Sugababes line-up of Mutya Buena, Keisha Buchanan and Siobhan Donaghy have regained the right to make music using the band's name.
The trio became the Sugababes back in 1998 and won acclaim for their debut single Overload.
The line-up went through various iterations over the years and the original trio lost the right to record and perform under the Sugababes name.
They have now announced that they are releasing the single Flowers, a cover of the UK garage classic by Sweet Female Attitude, their first music in six years.
Their last release was Flatline in 2013 which they released under the name Mutya Keisha Siobhan (MKS).
in a post on Instagram, the group said of their new single: "The Garage Classical album is a celebration of an important time in UK music. We grew up in the garage era and Flowers is a timeless classic - the perfect fit.
"We are so happy to finally be able to give a little something to our amazing supporters whilst we prepare for 2020. We hope you like it!"
The track appears on the Garage Classical album by DJ Spoony, which sees UK garage music re-imagined using the 36-piece Ignition Orchestra.
The Sugababes will make their on-stage return in a pre-recorded performance on The Graham Norton Show on Friday night.
