Did Kelly Clarkson just let it slip that she and husband Brandon Blackstock are expecting twins?!

In a new interview with 103.7's Leigh Ann & Courtney Uncorked exclusively obtained by ET, Kelly says "kids" -- plural! -- when talking about her current pregnancy.

"I'm gonna be everywhere once I get these kids popped out and done," the 33-year-old singer says. "That's why I look all ..." she laughs, trailing off.

However, Clarkson's rep shot down the potential rumors, confirming to ET that the singer is not expecting twins.

Kelly, who's been open in the past about suffering from severe pregnancy problems when she was expecting her first child, River Rose, also shares that it's not much easier the second time around.

"I have this thing, like one percent of women get, it's called hyperemesis," Kelly reveals to the radio show.

Hyperemesis gravidarum is a pregnancy complication characterized by severe nausea, vomiting and weight loss.

"It's horrible," Kelly says bluntly. "It's like the darkest places I've ever been in my life."

"I'm familiar with all day sickness," she also told CBS This Morninglast month. "It's pretty bad. I have to get IVs and fluids, I get so dehydrated. It's really bad."

Still, the original American Idol champ obviously couldn't be more overjoyed that she's expecting again with her hubby. Kelly adorably announced she was pregnant with her second child during her concert at the Staples Center in Los Angeles in August.

"I was not planning on announcing this. I'm totally pregnant again," Kelly said, laughing. "That was not planned. I just didn't want you to think I was crazy. Honestly, I'm just hormonal today. Nothing's wrong. I'm OK. I haven't vomited yet!"
