Jon Gosselin didn't wear anything by Ed Hardy — that we can see at least — when he arrived for Saturday's Wet Republic pool party at the MGM Grand.
We heard he'd brought his mother — Pamela Gosselin Castello — to Las Vegas, for her first visit to Sin City.
They were reportedly going to see some glitzy shows together.
But we bet Mommy was getting rubbed and waxed at the hotel spa and turning in early, conveniently leaving Jon to hit the tables, the slots and indulge in various other Vegas delights.
Jon hinted as much on his Twitter feed, tweeting "Making sure mom's pampered at the spa."
At the Saturday pool party, Gosselin chain-smoked, chugged bubbly and watched the poolside bacchanalia.
Is it just us or does Jon look about 10 years older since he started going through his midlife crisis?
