Jon Gosselin Parties The Night Away in Vegas

Ah, nothing like the single life in Las Vegas.

Reality TV dad Jon Gosselin made the most of his weekend trip to Sin City by hitting up the club scene last nite.

After dining at Mirage’s Stack Restaurant, Jon headed to Jet Nightclub with a crew of guys, where he spent most of the evening chain smoking, drinking Skyy Vodka, and texting.

However, in a strange twist, Gosselin ignored the many ladies who went up to his table, and focused on his friends and his phone.

Eyewitnesses did see him have one moment of fun, when he got on the sofa to dance to  DJ Class’s “I’m The Ish.” Yes, really.

Then the crew headed to XS Nightclub around 1am, where he stuck to his phone and drinking Grey Goose.

Dang. Wonder who the lucky lady was? You never know with this guy.
