The original Sugababes reunion has been dealt a blow after the reformed pop stars parted ways with their manager.
Keisha Buchanan, Mutya Buena and Siobhan Donaghy, who formed the band in 1998, have regrouped to perform under the title Mutya Keisha Siobhan, but their comeback has been soured by the loss of their longtime collaborator Felix Howard.
Howard, who co-wrote the band's debut 2000 hit Overload, is credited with bringing the girls back together for the reunion, but the trio will now be moving forward without him.
The band's public relations representative, Shoshana Stone, confirmed the news but called Howard's exit a "mutual parting of ways".
A source tells British newspaper the Sunday Mirror, "They didn't think things were working out and wanted to get a new manager. Everyone was really shocked. Felix knows how to manage a band and is a good guy for the job. But they wouldn't have it and thought it best to get a new manager before they started releasing the new music. There's no bad blood."
Donaghy was the first to leave the Sugababes and after she walked out, Buena and Buchanan both later quit and the group continued with a different line-up.
