Kelly Clarkson is officially a mother-of-two!

The 33-year-old singer gave birth to her second child, a boy, on Tuesday, April 12, confirming the news herself later in the week.

"Our little baby boy has arrived!! Remington Alexander Blackstock was born 4/12/16 & he is healthy & we couldn't be happier or more in love!" Clarkson tweeted on Thursday morning.

This is Clarkson's second child with her husband, talent manager Brandon Blackstock. Clarkson is already a mother to her 1-year-old daughter River Rose, and is a stepmom to Blackstock's two children from a previous marriage.

It's safe to say the American Idol champ has been eager to give birth leading up to the big day. Responding to a Trisha Yearwood tweet earlier this month of a coffee mug reading, "I can't even," Clarkson wrote, "Girl, this describes my day. I feel like Rachel on Friends w/this baby #getoutgetoutgetout hahaha."

She's also made it no secret that she's had extremely difficult pregnancies with both River and her newborn son.

"Honestly, the first one was really rough, and I was like, 'Oh, it can't happen again,' and no it happened, like, way worse this time," Clarkson shared in a radio interview with Australia's KIIS FM last month, explaining that her ailment is "100 times worse" than morning sickness. "I just get hospitalized, and I have to get fluids. It's just, like, my body was not made to be pregnant."

"I wish I was like the girl that ... it's beautiful, but it's not," she added.

And if all goes according to plan, this will be her last pregnancy.

"Oh, no, we are done," she laughed. "Oh good Lord, yes, I can't be pregnant again. This will be our number four total, so we're good."

One thing she can definitely count on is her husband of two years being a great father to their kids.

"Watching my husband love on his daughter all the time, you know, go to her events and just be there and, like, be present is, like, hard to watch but beautiful to watch," Clarkson told Ryan Seacrest during a radio interview in February, fighting back tears. "But it's awesome because I know that my kids are going to have that."

"I cannot imagine not seeing this kid to his or her full potential and just seeing what she's going to do, what she's going to be like," she continued.
