Kelly Clarkson and husband Brandon Blackstock welcomed a baby daughter on Thursday.

"Our baby girl River Rose Blackstock arrived on June 12th!" Clarkson tweeted on Saturday, June 14. "Thank you everyone for all of your well wishes! Brandon and I are on cloud 9!! :)"

Clarkson and Blackstock got married in October 2013, and the following month they confirmed that they were expecting their first child together. Prior to that, the American Idol alum was very open about wanting to expand their family. (Blackstock has two children from his previous marriage.)

"More than anything, next I want a baby. Lots of them!" she told Us Weekly last fall. "My record label is freaking out because all I can talk about now are babies. We're really excited and want to get our family started." Clarkson added in an interview with Elvis Duran and the Morning Show back in October, "I want two kids. Two more, that is. I've already got two!"
