The Sugababes singer is reportedly set to fly back to Britain on Thursday (05.11.09) after spending just under three weeks being treated for nervous exhaustion at a private clinic in Germany. A source told Britain’s Daily Star newspaper: "Amelle is over the moon to be leaving the hospital at last. "She feels like a new person and can’t wait to get back to work and put this sad situation behind her. "The clinic`s programme includes acupuncture, as well as group therapy sessions, building up confidence and tackling insecurities. "Amelle`s been doing a lot of exercise like hiking and running and said she`s in a good place. She`s ready to move forward with her life and get back to work with the band." Amelle, 25, took time out from the pop trio after recent stresses within the band - which saw original member Keisha Buchanan replaced by Jade Ewen - became unmanageable. She had allegedly also struggled to cope with death threats from fans of Keisha and was described as a "danger to herself". Amelle is set to throw herself straight back into work with Jade and Heidi Range when she returns home. The `About A Girl` singers have been forced to put back the release of their new album, `Sweet 7`, to February next year. The record was originally due to be released on November 23 with Jay-Z`s Roc Nation and Island Records. They now need time to practice the new songs as a group and record girl Jade`s voice on the album.
