Kelly Clarkson Reveals Gender of Her New Baby

The singer has one other child, 1-year-old daughter River Rose.

— -- Two months after singer Kelly Clarkson unexpectedly spilled the beans that she is pregnant, the pop star has revealed the gender of her new baby.

In August, Clarkson announced her pregnancy during her concert at the Staples Center in Los Angeles, later admitting that the baby reveal "was not planned."

Clarkson posted a photo on Instagram of her first child, River Rose, smiling on a slide, and revealed her new baby's gender in the caption underneath.

"In other news, River's gonna have a little baby brother," Clarkson captioned the photo along with the hashtag #itsaboy. "We're so excited," she continued.

Clarkson and her husband Brandon Blackstock have been married since 2013, and have one other child, River Rose, together. Blackstock has two children from a previous marriage.
