The stars of TLC’s defunct reality-TV series “Jon and Kate Plus 8” have reunited -- at a family yard sale. Five years after the Gosselins were divorced and ended their hit series’ three-year run, they made an appearance alongside their eight kids at Kate Gosselin’s highly publicized yard sale in Wernersville, Pennsylvania, on Saturday. Unfortunately for Jon Gosselin, his presence at the event didn’t appear to thrill his ex (her rumored boyfriend, and married bodyguard Steve Neild) -- was also there.

Kate, 39, appeared “none too pleased” about Jon’s arrival and sported a “stern demeanor” after spotting him, according to a report from the Daily Mail. In photos of the yard sale, Kate can be seen looking confused at his arrival as their daughter Mady, 14, looks on. In another image, the former couple appear to come together to converse with their daughter Alexis, 10. Their other children Cara, 14, and 10-year-old sextuplets: Aaden, Collin, Leah, Joel and Hannah, also attended the sale. The "Gosselin Family Yard Sale" was taped for an upcoming “Kate Plus 8” special that will air in December on TLC.

Jon's role in the yard sale remains unknown, but the 37-year-old has reportedly been going through a rough time financially after losing his job at a credit card company. A source told Us Weekly that Jon was evicted from his home in rural Pennsylvania after missing payments. He's reportedly so desperate to raise cash that he even thought about blackmailing his ex-wife, although the two have previously shared their differing philosophies on parenting their children. (She's expected to earn up to $40,000 per episode when “Kate Plus 8” returns.)

“[Jon] has no stable job, no steady income and now he’s trying to tell Kate that if she doesn’t give him a cut of the money, he will claim the kids hate filming and they are being forced to do it,” an insider said.

“He’s all bark and no bite. Kate has absolutely no intentions whatsoever of giving him any money,” another source said.

In July, Radar Online reported that Kate was instructing the babysitters to closely monitor her children’s phone calls with their father.

“ALWAYS listen with one ear to hear what they’re saying,” Kate’s babysitting manual reportedly reads. “You are always my eyes and ears and need to report everything you see and hear!!!”

The yard sale in Pennsylvania reportedly included a majority of her children's items, including toys, books and clothing. Kate has denied that the yard sale was held to ease the family's financial burdens.

“Fyi: Yardsales r NOT $ makers. Purging is a gr8 organizational skill, especially after construction/losing major storage space! #StopRumors,” Kate tweeted Wednesday.

Kate did take time to pose with fans for photos at the yard sale. She said the event, which reportedly donated some of the proceeds to a local animal shelter, was a success.

“We had a memory filled X at r yardsale! Met hundreds of THE nicest ppl & saw many old friends 2! PLUS raised tons of $ for ARL Berks County,” she said. “Thank you ALL 4 coming out to meet us! My kids had fun w ur kids on playground! And thx 2 for your generous donations to ARL Berks County!”
