Kelly Clarkson Welcomes Baby Girl, River Rose

Kelly Clarkson and her husband, Brandon Blackstock, have welcomed their first child, a little girl.

The "American Idol" winner and "Breakaway" singer broke the news via Twitter Saturday, stating that she and her husband are "on cloud 9!!"

"Our baby girl River Rose Blackstock arrived on June 12th! Thank you everyone for all of your well wishes! Brandon and I are on cloud 9!! :)" Clarkson shared via Twitter.

Clarkson announced the pregnancy last Fall, just weeks after she and Blackstock tied the knot. She also spent a good part of the Fall touring and performing, including a stint with Maroon 5 and an NBC Holiday special.
