Jon Gosselin grows more appauling every day and this day is no exception. Radaronline.com got their hands on a photo of Jon's most recent sleep over guest and she happens to be the same woman he recently hired to baby sit his kids during the 96 hours a month he spends with them.

This passed Saturday Jon spent the night with Stephanie Santoro, 23, a cocktail waitress, single mom and aspiring model whose online resume reveals she's willing to pose nude!

Jon and Stephanie, who works part-time at Legends, Jon's favorite night spot in Reading, Pa., spent Saturday night there, with Stephanie sitting at his table most of the time.

They left together at a little before 3 a.m., according to RadarOnline.com. (The club closed at 2 a.m. but they stayed inside.) They drove together in Jon's car back to the family home in Wernersville where Stephanie spent the night in Jon's apartment over the garage.

Stephanie stuck her head out at approximately 7:15 a.m. Sunday, wearing the same outfit as the night before. Jon called her back in and soon they left in separate cars.
