She finally popped!

Kelly Clarkson has welcomed a son with husband Brandon Blackstock, the singer announced on Twitter Thursday. "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!" she wrote. The newest addition joins the couple's 2-year-old daughter River Rose.

The American Idol alum announced she was expecting her second child during a concert at L.A.'s Staples Center back in August. "I was not planning on announcing this but I'm totally pregnant. I didn't want you to think I was on pills or something! Everything is great. I haven't vomited yet, that's a win!" she told the crowd at the time.

Congrats to the happy family!
