The singer insisted that the original Sugababes lineup will put out a track before 2013.
"You will definitely have music this side of 2013," she told Jon Hornbuckle at the Look Magazine fashion show. "Maybe not the album but at least some tracks!
"The new music will be so different, it's going to be - dare I say it - quite Sugababes-ish. We all have so many different influences from the '90s and onwards."
Mutya Keisha Siobhan recently revealed that they have written a song for their upcoming album with ex-All Saints star Shaznay Lewis.
Earlier this year the trio parted ways with their manager Felix Howard, who worked with them during their 2000 album One Touch.
