Mutya has announced that she's leaving the Sugababes and a new member is going to be joining the pop trio.
The new member - who has been already chosen - will be revealed in the "next 24 hours" says the band's website.
Mutya said her decision to quit the band was based on personal reasons, and was a very difficult one to make.
She said the band were in "total agreement" a new member should join and added: "She's so lucky to be getting one of the best jobs in the world!"
Remaining Sugababes Heidi Range and Keisha Buchanan
Mutya had her first baby, a little girl called Tahila, in March this year.
Muyta leaving means Keisha is now the only original member of the Sugababes still in the band.
She said: "Obviously, it goes without saying that we will all miss Mutya, but we also knew there was still a place for bringing in somebody new who could help us carry on taking the Sugababes brand of music forward."
The new Sugababe is going to be kept pretty busy in the coming months, with the band's own UK tour in March and April as well as supporting Take That on their mega tour too.
