Meet Jon Gosselin’s New Baby-Sitter/Girfriend

Jon Gosselin’s newest hookup is pulling double-duty at the Gosselin household.

Stephanie Santoro, a 23-year-old aspiring model, was allegedly hired by the Jon & Kate Plus 8 dad to babysit his kids. But it seems as though Jon is mixing business with pleasure.

Radar reports that the single mom has told people that Jon hired her to watch over the Gosselins’ mega-brood. However the two were caught having a sleepover after spending Saturday evening drinking together.

The couple spent the evening partying at Jon’s favorite bar Legends (where Stephanie works part-time). An eyewitness dished that they left together around 3 a.m. and drove together in Jon’s car back to the Gosselin house, where Stephanie spent the night in Jon’s apartment over the garage!

Stephanie was caught by paparazzi sticking her head out of his apartmenert around 7:15 a.m. on Sunday, wearing the same clothes as the night before. Then, Jon called her back inside, where they stayed until leaving in different cars shortly after.

That’s some kinda babysitter! A babysitter who designates on her modeling profile that she’s willing to pose nude, we might add.

We wonder what his other girlfriends have to say about this one? Stay tuned…
