Jelly Roll unleashes crude jokes about Trump's weight on 'Kimmel', 'from one fat pig to another'

Country music star Jelly Roll , who previously said he was not political, mocked President Donald Trump's weight, physical fitness and approval ratings Monday night in Los Angeles while guest-hosting "Jimmy Kimmel Live!", while using the president's appearance at Washington's Freedom 250 Grand Prix and recent physical as material for his opening monologue.

"Well, Mr.

President, from one fat pig to another, take it from me that physical fitness is very important.

And trust me, you’ll be happy to see your penis again," Jelly Roll said.

"It’s crazy.

Think about this, y’all.

In the last few years, I’ve lost 300 pounds.

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

Fox News Digital reached out to the RNC for comment but did not immediately receive a response.

TRUMP TAKES HONORARY LAP AROUND INDYCAR TRACK IN WASHINGTON AHEAD OF FREEDOM 250 GRAND PRIX A Reuters/Ipsos survey released last week placed Trump at 33% approval and 64% disapproval, tying the lowest approval rating across both of his terms, Fox News Digital reported .

"President Trump has signed the largest middle-class tax cuts in history, lowered the cost of prescription drugs, sealed the border, driven violent crime to the lowest level in nearly a century, unleashed an energy revolution and sent Americans’ 401(k)s climbing to record highs," White House spokesperson Olivia Wales told Fox News Digital in response to questions about the polling.

"President Trump is cleaning up Joe Biden’s mess, and there is more work to do, but the United States of America has never been stronger," she continued.

Jelly Roll began the political portion of the monologue by discussing Sunday's Freedom 250 Grand Prix .

Trump and first lady Melania Trump completed an honorary lap in the presidential limousine before the president waved the green flag to start the race, which Kyle Kirkwood won, according to OutKick .
