Scott was joined by his ex-girlfriend, Kourtney Kardashian, her sister, Khloe Kardashian, and their close pal, Malika Haqq. The girls dressed to impress for the soiree, with Malika sporting an LBD that featured a plunging neckline and thigh-high slit, while Khloe impressively pulled off a skintight pink House of CB latex dress and Kourtney donned a bright green printed Versace dress.
The birthday boy kept it slightly more casual in distressed denim jeans, a basic black T-shirt and satin palm leaf bomber jacket.
The foursome kicked off their festivities with dinner and cocktails at STACK Restaurant and Bar before heading to the club around 1 a.m. Once they were inside the venue, they took a seat at a VIP table right behind DJ Shift and Kid Conrad's DJ booth.
They didn't forego desert at the soiree, as cocktail waitresses presented Scott with a black-and-white three-tiered Rolls-Royce themed cake that read "Happy Birthday Scott."
According to an eyewitness, Scott and Kourtney were whispering to each other inside their booth. Scott also exchanged a lot of laughs with Khloe, who was spotted snapping selfies with Malika and the DJs throughout the night.
Around 1:20 a.m., the DJs wished Scott a happy birthday and played 2 Chainz's "Birthday Song," which features lyrics like, "It's your birthday, it's your birthday" and "all I want for my birthday is a big booty hoe."
