If you're going to party after a major breakup, Las Vegas is probably the place to visit.
Despite the turmoil surrounding him, Disick was excited to be in Vegas, sharing a photo of the venue -- complete with his name stitched into a pillow -- before the party got underway.
He even posted a picture of his pre-party meal from Stack, a restaurant he said he loved that's also located inside The Mirage.
After the meal, Disick appeared to be in good spirits. "I'm excited," he told reporters on the red carpet. "I haven't been here in a while, so it's good to be back."
When asked directly how he was staying positive with all of the difficulties in his life right now, he paused before cautiously responding that he was taking "every day a day at a time."
The dad-of-three may be known for his hard partying ways, but even he knew that it was necessary to be on his best behavior at this very public outing. Even though he was surrounded by cocktail waitresses shooting confetti and props with his face on them, Disick didn't go crazy Friday night.
A source tells ET that despite also having tons of girls surrounding his VIP table, Disick, dressed in a dapper gray suit, mostly kept to himself. He hung out with a few of his old friends who were visiting from New York -- a posse he described as "nothing crazy" -- posed for photos and left 1Oak by 2 a.m.
All hail, Lord Disick.
It's a major difference from last week, when the 32-year-old New York native gave just two days notice before canceling an Atlantic City nightclub appearance. It was his second cancellation -- this night at 1Oak had actually been rescheduled from its original July 10 date.
Just hours before the July 24 gig, the Keeping Up with the Kardashian star posted a serene beachside photo, saying, "This is what I need right now."
Sounds about right.
Disick's split from Kardashian came after he was spotted getting touchy-feely with an ex-girlfriend in Monaco three weeks ago. After moving out of Kardashian's Calabasas, California, home earlier this month, Disick has been living in Beverly Hills — where a number of women were recently seen.
