Kelly Clarkson has given birth to a baby boy!

The singer, who is already mom to the adorable River Rose (who's turning two in June), announced the extension of her family on Twitter on Thursday (April 14). Welcome, Remington Alexander Blackstock!

Clarkson had announced her second pregnancy during a show at Los Angeles' Staples Center in August, telling the crowd:

"I wasn't planning on announcing...[I'm] totally pregnant. That was not planned. I just didn't want you to think I was crazy or something. Honestly, I'm so hormonal today. Nothing's wrong. Everything's great. I haven't vomited yet."

Remington—quite the regal name, don't you think?—is her second child with husband Brandon Blackstock, whom she married in 2013. She is stepmother to Blackstock's two children from a previous marriage.

Clarkson took her baby bump to the stage for the last episode of American Idol, pretaping her emotional performance since the live show would be too close to her due date.
