Kelly Clarkson welcomes baby girl with Brandon Blackstock

Kelly Clarkson and husband Brandon Blackstock have a new baby girl.

“Our baby girl River Rose Blackstock arrived on June 12th!,� the pop star tweeted Saturday. “Thank you everyone for all of your well wishes! Brandon and I are on cloud 9!! :)�

Clarkson, who during her pregnancy suffered horrible morning sickness, predicted way back in November that the little one would be a girl.

“She’s killing me,� Clarkson said at the time. “Of course it’s a girl, causing the trouble.� That guess was confirmed by doctors in January.

The “Catch My Breath� singer told Ellen DeGeneres in December that they’d already picked a “random� but not weird name for the child, one that worked whether they had a boy or a girl. We’re guessing “Rose� was added after the gender ticket was finalized?

Clarkson, the first “American Idol� winnner and one of its most successful, married music manager Blackstock in a small Tennessee wedding in October after dating since late 2011. She’d tweeted word of their engagement on Dec. 15, 2012.

River is a first child for the singer. She’s the third for music manager Blackstock -- happy Father’s Day, dude! -- who also has a son and daughter from his first marriage to Melissa Ashworth.
