First, he had dinner with his mom at Stack Restaurant, where they ate lobster tacos and sashimi and washed it down with pomegranate martinis and vodka Red Bulls.
After eating, Jon hit Jet Nightclub at The Mirage. He left Mom behind, but brought along his bodyguard, who was wielding confidentiality agreements for fellow clubgoers. Seriously.
Did anyone actually agree to keep quiet about Jon's partying, like this elegant lady in the blue minidress?
"They had confidentiality agreements with them but they never did hand them out," a source tells E! News, adding that eyewitnesses didn't see anyone actually sign them.
The infamous father of eight kept it classy in the club, chain-smoking and ordering a bottle of Dom Pérignon for $650. He left a generous tip before heading over to XS at 1:30 a.m. for more partying.
Luckily, his late-night clubbing didn't make him miss his flight home this morning.
"On the plane, can't wait to see the kids!!!" he just posted on his new Twitter.
