On TV, he is a harried father of eight with a wife who is constantly on his case, so it’s not surprising that Jon Gosselin needs to blow off some steam.

Apparently The father of twins and sextuplets has been living it up in Huntingdon, Pa., where his mom resides. He turned up uninvited at a Feb. 6 party thrown by Juniata College seniors Erin Albert and Mariel Little – and ended up playing the drinking game beer pong with members of the women’s volleyball team!

word was that “He was dirty dancing with several of them, making out, kissing them on their necks and mouths.” OMG say it isntso Jon!!!!

“He was obliterated,” says Pott. “Juniata girls were flirting with him and he was loving it and having a great time.”

Can you imagine paying child support on 8 kids? Good God!

God he looks wasted!
