It's a girl for Kelly Clarkson and music manager husband Brandon Blackstock, according to reports from People. The "Stronger" singer delivered daughter River Rose on Thursday but waited until today to tweet the good news. "Thank you everyone for all your well wishes! Brandon and I are on cloud 9!!" she wrote.

This is Kelly's first child -- Brandon has two children, Seth and Savannah, from his first marriage.

The couple, who tied the knot in Tennessee last October, made it no secret that starting a family was a top priority for them. Pregnancy threw the former American Idol a few curveballs, most notably serious bouts of morning sickness, but she was confident early on that she would have a daughter. In January, when her suspicions were confirmed, she tweeted, "I knew it! Only a girl could cause this much drama with all this vomiting!"

Congratulations to the new parents -- and happy Father's Day, Brandon!
