Kelly Clarkson let it slip she may be having more than one child during a recent radio interview.

Speaking with hosts of Leigh Ann & Courtney Uncorked on 103.7, Clarkson, married to Brandon Blackstock, used the plural when discussing her pregnancy, "Entertainment Tonight" reports.

"I'm gonna be everywhere once I get these kids popped out and done," the soon-to-be mother of two or more said over the phone. "That's why I look all..." she added before reportedly trailing off.

Although Clarkson mentioned "kids" instead of the single baby boy she announced last month, her reps deny rumors she's having twins, according to reports.

Clarkson recently shared a "Game of Thrones"-themed holiday card featuring husband Blackstock, their daughter River Rose and Blackstock's two children. The image included the motto "Winter is Coming."

The original "American Idol" winner, 33, recently detailed her rough experience being pregnant for the second time.

"I'm familiar with all-day sickness," she said during a television appearance in November. "I have to get IVs and fluids because I get so dehydrated. It's really bad."
