BIG-GUT GREG GOES BELLY-UP!

GASBAG Greg Gutfeld isn't just puffed up with hot air — the Fox host's flabby figure has made him the laughingstock of the newsroom, sources tell The National ENQUIRER. The 60-year-old's more svelte coworkers were snickering at pictures of the porky pundit walking shirtless on the beach in Miami with his wife, Elena Moussa, on June 27.

"They're saying Greg needs to do something about those belly rolls and man-boobs and were making jokes about it," an insider says.

The photos were especially laughable since Greg was once a fitness nut and was formerly the editor-in-chief of Men's Health.
