Gosselin nanny affair rumors are rampant, now that Jon Gosselin’s nanny, Stephanie Santoro, spilled the beans to In Touch Weekly magazine that she and Jon had sex!

Whether or not the Gosselin nanny’s affair news is true or not remains to be seen, but Santoro tells In Touch Weekly that it all started when Jon Gosselin asked for a massage.

Santoro, 23, gave said massage and next thing you know… they’re in the hot tub, with the nanny saying she was “afraid one of the kids was going to pop their heads out, but he told me to relax.”

The Gosselin nanny said Jon “ran in to make sure all of the kids were asleep, and we went back into the apartment that is over the garage. We continued what was going on in the hot tub, and then he fell asleep afterward.”

Sexy…

The nanny claims that she and Gosselin had sex nine times (why is that “nine times” Ferris Bueller quote running through my head?) and that Gosselin “wasn’t terrible, but it wasn’t the best I ever had.”

Burn!
