“Jimmy Kimmel Live” guest host Jelly Roll scolded President Donald Trump for his fatphobic insults, then hit him where it hurts. (Watch the video below.)

On Monday’s show, the performer, who has struggled with his own weight, urged the president to drop a few.

“Well, Mr. President, from one fat pig to another, take it from me, that physical fitness is very important,” he said. “And trust me, you’ll be happy to see your penis again.”

Jelly Roll riffed on a recent Washington Post article focusing on the president’s reported weight gain while the singer noted he’s lost more than 300 pounds over the last few years.

“That means I’ve lost an entire Donald Trump,” he said to cheers. “And let’s be honest, based on his approval rating, it seems like most of the country wants to do the same thing.”

Jelly Roll stayed with the theme a bit longer.

“We shouldn’t be making fun of the president for his weight because we know that he would never do that to other people,” he snarked, prompting a montage of Trump’s body-shaming.

Jelly Roll added, “Well, if that ain’t the pot calling the kettle fat.”
