Behold - Jon Gosselin’s newest plaything! This one’s named Stephanie Santoro. She’s a 23-year-old aspiring model and single mom who babysits Jon’s kids for some extra cash on the side.  She’s also a cocktail waitress at Legends - that bar that Jon enjoys taking his various women to.

Stephanie was spotted drinking with Jon at Legends last Saturday night.  According to Radar Online, the couple left the place at 3 a.m., and headed over to Jon’s house for a little sleepover in his apartment above the garage.  The paparazzi waited outside of Jon’s house all night long for Stephanie to leave, and she finally did around 7:15 a.m. the next morning.

Several days before the sleepover, Stephanie was spotted at the Gosselin house with her 2-year-old kid for a playdate with the Gosselin brood.  When asked, she neither confirmed nor denied having a relationship with Jon.
