From American Idol:

Season 7's Carly Smithson became a mom on September 30th, when she and her husband welcomed a baby girl named Olivia Mabel Smithson. It was worth the wait for Carly, who was 11 days overdue. View a photo of beautiful Olivia, here.

A month ago, Carly wrapped up her 22 month gig with Cirque du Soleil's Viva Elvis. When Season 11 auditions happened on the Viva Elvis stage, Carly came to visit. Now, Carly will focus on recording her own music with We Are The Fallen, and she will focus on her upcoming role as a mom.

Congratulations, Smithson family!
