Sugababe expecting baby girl

Sugababe star Mutya Buena is expecting a baby girl but she's determined to keep her chosen name a secret.

The five-months pregnant Round Round singer refuses to follow the celebrity trend of giving her baby an unusual name but she's already decided on a "quirky" moniker.

Buena says: "I'm finding it really hard to believe I'm pregnant.

"I do know what it is…I'm not sure if I should be keeping it a secret but I've got a little girl.

"I like quirky names but nothing too weird. I'm keeping that one secret."
