Kelly Clarkson wants a ''chunky'' baby.

The 'Since U Been Gone' singer is pregnant with her first child with husband Brandon Blackstock, and says she hopes her baby - which she thinks is going to be a girl - has plenty of meat on her.

She told America's OK! magazine: ''I want chunky babies. I just love chunky babies. I want to bite their chunky arms and thighs. They're just so cute!''

Kelly, 31, and Brandon - who also has children Savannah, 12, and Seth, six, from a previous relationship - have got some names in mind for their young one, but won't say whether they will be traditional or modern.

She added: ''We're going with a little bit of both. We're keeping it in the family, but also doing something cool for us.''

Kelly also loves helping out with the children's school work.

She added: ''I honestly love the homework. I love doing homework with children. You're helping with their education, you're helping with social issues and all that.''
