Don't tell Kim Kardashian!
Kim's short-lived husband had a great time with his sports buddies and was joined by Griffin too.
The pair were surrounded by girls at the bash and seemed to be exchanging stories.
A source revealed: "Blake was out with the boys and it was a cliquey sports crew with Kris and Blake on the same table on a VIP platform above the main platform.
"They seemed to be having a great time and Blake later slipped away to attend Kendall's private party at a rented residence.
"She probably wouldn't be too happy to know he was hanging out with Kris as the family can't stand him."
Kim Kardashian and Kris Humphries got married in August 2011 but their marriage only lasted 72 days.
