Kelly Clarkson shares first photo of daughter

Kelly Clarkson is giving fans the first look at her newborn baby girl.

The "American Idol" winner officially introduced her daughter, River Rose Blackstock, in a photo shared on her social media pages Friday. In the sweet snapshot, the little girl can be seen sleeping in a vintage-looking carriage.

"Here is our beautiful baby girl River Rose; 6lbs 6oz, 18 inches, and the greatest thing on the planet," she tweeted.

River, born June 12, is the first child for Clarkson and her husband, Brandon Blackstock (who also has two children from a previous relationship). The couple tied the knot last October, and announced in November that they were expecting.
