Fox News host Chris Wallace was dishing up some humble pie after he made a fat joke about singer Kelly Clarkson.

Wallace is the latest to rip on the "American Idol" winner during what was supposed to be a political radio show Saturday.

While a guest on the "The Mike Gallagher Show," the two men were talking about fat-shaming and soon enough the host brought up Clarkson's name.

"Have you seen Kelly Clarkson? You know the singer, Kelly Clarkson? Holy cow, did she blow up," Gallagher said

Wallace looked as if he was defending the artist by replying, "Really? Do we want to talk about some of your friends? Kelly Clarkson's got a lovely voice."

But added, "She could stay off the deep dish pizza for a little while."

Wallace issued an apology on Sunday for the comments.

"I sincerely apologize to Kelly Clarkson for my offensive comment. I admire her remarkable talent and that should have been the focus of any discussion about her."
