Fox News host Greta Van Susteren blasted colleague Chris Wallce in a Friday blog post, calling on him to apologize over an "obnoxious" comment he directed at singer Kelly Clarkson.
"Chris Wallace owes Kelly Clarkson an apology," the title of her blog post read.
Van Susteren was referencing a comment the "Fox News Sunday" host made during a radio appearance on Mike Gallagher's show.
"She should stay off the deep dish pizza for a little while," Wallace said, in response to a question over Clarkson's weight.
Van Susteren did not find the comment amusing.
"This 'snickering' about her weight is obnoxious," she wrote. "He should apologize."
