Chris Wallace Apologizes for Kelly Clarkson Weight Jab

What doesn't kill you makes you… apologize.

Chris Wallace, the host of Fox News Sunday, issued an apology to Mediaite for the comments he made about Kelly Clarkson.

"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," he said in a statement.

Wallace and conservative radio host Mike Gallagher got into a discussion about fat-shaming on Gallagher's radio show on Friday.

"Have you seen Kelly Clarkson?" Gallagher asked. "Holy cow, did she blow up."

Initially, Wallace tried to evade the comment, noting American Idol winner Clarkson has "a lovely voice." But later, he came back to it, saying, "She could stay off the deep-dish pizza for a little while."

Wallace's Fox News colleague Greta Van Susteren wrote on her blog that Wallace should apologize for his remarks.

Mediaitepublished his apology on Sunday.

Clarkson gave birth to daughter River Rose in June 2014, and has since come under fire for her size. She defended herself this past week week on The Ellen Degeneres Show, saying her weight fluctuates.

"Sometimes I'm more fit and I get into kickboxing hardcore," she told DeGeneres. "And then sometimes I don't and I'm like ... I'd rather have wine."
