DO you want fries with that burger?

In order to make ends meet, one-time reality TV star JON GOSSELIN has taken a job as a waiter and bus boy at Emily’s pub in rural Beckersville, Pa.

What’s more, the former computer programmer, who divorced his wife Kate in 2009, is living in a cabin in the woods to save money.

“Jon has really hit rock bottom,” said a source close to the co-star of the former cable TV hit “Jon & Kate Plus 8.”

“Just a few years ago, he was jetting off to France to hobnob in St. Tropez, sipping champagne on a yacht. Now he’s waiting tables at a pub! Working the weekday lunch shift, he can’t possibly be taking home more than $40 or $50.”

The ENQUIRER recently approached Jon at the eatery, which was once a historic hotel.

 He said he was there to “volunteer” and declined to comment further.

But Emily’s pub staffer Leah Littlefield tweeted: “Jon Gosselin is the new server at my work” and “…I’m ahead of him right now, too. I’m hosting, he’s serving.”

At one time, Jon was on the hook for a whopping $22,000 a month in child support. Then last year, Kate relieved him of all current and future child support obligations.

But she recently slapped her ex with a lawsuit alleging he and a writer had illegally hacked into her e-mail accounts, phone records and bank accounts for a book titled, “Kate Gosselin: How She Fooled The World.” It was pulled from soon afterward.

Jon became a household name when the couple’s reality show took off on the TLC network in April 2007.

“Now Jon doesn’t know what he’s going to do,” said the source. “He can’t defend himself against Kate’s suit. He’s just struggling to pay the rent on his cabin in the woods.”
