The 'Since U Been Gone' singer said she hopes her baby, which she thinks is going to be a girl, has plenty of meat on her, reported Contactmusic.
"I want chunky babies. I just love chunky babies. I want to bite their chunky arms and thighs. They're just so cute!," she said.
Clarkson, 31, and husband Brandon Blackstock, who also has children Savannah, 12, and Seth, six, from a previous relationship, have got some names in mind for their young one.
"We're going with a little bit of both. We're keeping it in the family, but also doing something cool for us," she added.
