The singer just took to Instagram to reveal the gender of her second child alongside an adorable picture of daughter River Rose.
"In other news, River's gonna have a little baby brother :) #itsaboy We're so excited!" she captioned the cute candid.
In the pic, her tiny tot is sporting an orange sweater, jeans and a giant grin as she sits on top of a slide.
The "American Idol" winner announced her pregnancy back in August during her concert at the Staples Center in Los Angeles. She was getting into a performance of the emotional song, "Piece By Piece," -- a tune describing how her husband is a better father to their daughter than hers ever was growing up -- when she kept getting choked up.
“I was not planning on announcing this, I'm totally pregnant," she then blurted out, sending the crowd into a frenzy. "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."
We can't wait to see little River with her baby bro. Congrats, Kelly!
