For the second time in less than six months, reality personality Jon Gosselin, star of the popular TLC series Jon & Kate Plus 8, has sparked speculation that he is cheating on his notoriously outspoken wife, Kate, after being spotted leaving a nightclub near the family’s Pennsylvania club accompanied by a mystery woman.

Us Weekly claims: The dad of 8 — kids are twins Madelyn and Cara, 8, and 5-year-old sextuplets, Aaden, Joel, Collin, Hannah, Leah and Alexis — was overheard yelling, “Hey, babe! Babe! Give me my jacket!” before climbing into his Nissan Nismo….As cameras began snapping, he panicked, urging his female friend to “get in the car!” before speeding off hastily — without even turning on the headlights.

Sounds like Jon’s got some explaining to do!

Neighbors of the family tell the tab that divorce is looming for the new First Family of Reality TV.

While flies on the wall are insistent that Jon is creeping, in an e-mail statement to Us, the devoted dad vehemently denied any wrongdoing.

He writes: “I went to Legends to speak to the owner. A friend of mine wanted to check out my car, so I let her drive it to her car,” he says. “Yes, I have female friends — but that is all she is. I’m not going to end my friendships just because I’m on TV.”
