Big weekend for Jon Gosselin.
First, his sit-down with Good Morning America, then his highly anticipated pool party at Wet Republic at the MGM Grand Hotel & Casino in Las Vegas.
The reality dad turned eligible bachelor left ladylove Hailey Glassman behind, opting instead to bring his mother, Pamela Gosselin Castello, along to the event.
"Glad to be at MGM," Gosselin told reporters as he made his way to a private poolside bungalow, taking advantage of ample photo ops with bikini-clad girls.
It wasn't all fun and games for Gosselin...
Jon faced several critics throughout the party, shouting things like: "Go sleep with that 18-year-old" and "We love Kate!"
But Gosselin kept his cool, spending most of the day smoking cigarettes, drinking champagne and socializing with hundreds of partygoers.
Jon even started his own official Twitter, tweeting about Cirque Du Soleil and the rest of his weekend: "Another beautiful day in Las Vegas. Making sure mom's pampered at the spa."
Afterparty plans? Jon will hang around Vegas until Monday, when he plans to once again meet with Ed Hardy designer Christian Audigier to discuss their rumored clothing line.
"Everything is in the works," Gosselin hinted to reporters on the Wet Republic blue carpet.
