Kelly Clarkson Announces Baby's Gender: Boy or Girl?

Kelly Clarkson announced on Friday that she's having a baby boy.

The 33-year-old singer spilled the beans on the gender of her second child over social media, according to People.

Clarkson shared a snapshot of her 16-month-old daughter River Rose at the top of a slide with the caption, "In other news, River's gonna have a little baby brother :) #itsaboy We're so excited!"

The "Invincible" singer first revealed she was pregnant with her second child with husband Brandon Blackstock in August during a stop in Los Angeles on her Piece by Piece tour.

"I was not planning on announcing this, but ... I'm totally pregnant," Clarkson said while crying on stage during the show.

"My makeup artist is backstage hating me right now. I just don't want you to think I'm on pills or drunk ... I'd like to apologize to my husband. That was not planned. I just didn't want you to think I was crazy or something. Honestly, I'm just so hormonal today. ... I haven't vomited yet. That is a freakin' win, y'all."

In a previous interview in February, Clarkson spoke about wanting to have more kids.

"I want another one ... But I'm just a little frightened because [River is] so perfect," she said. "I feel like something horrible's gonna come out of me. Because she's so great - like, the yin to her yang ... But I won't put that out there. I'm gonna project happiness."

The singer was recently forced to cancel the remainder of her Piece by Piece tour due to doctor's orders that she remain on vocal rest.

Clarkson released her latest album, "Piece by Piece," on Feb. 27. The album, which topped the U.S. Billboard 200 chart, has produced the singles "Heartbeat Song" and "Invincible."
