Former American Idol finalist Carly Smithson has given birth to a baby girl.

The singer, who competed on the seventh season of the hit talent show, and her husband Todd welcomed their first child on Sunday (30Sep12).

Sharing a photo of little Olivia Mabel Smithson on, she writes, "I’d like to introduce you all to my new baby."

After leaving the Idol competition in 2008, Smithson went on to form a new band, We Are the Fallen, with ex-members of rock group Evanescence.
