NEW YORK (AP) -- Kelly Clarkson has something to sing about: She's celebrating the birth of her first child.

The Grammy winner announced the arrival of her daughter, named River Rose Blackstock, in a Saturday post on Twitter.

She says the baby arrived on June 12, and she and her husband are "on cloud 9."

Her rep confirmed the tweet.

The 32-year-old singer, known for hits like "Stronger" and "Since U Been Gone," married music manager Brandon Blackstock last year.
