When you take Sin City, you have to take it by storm! And while wearing a hot dress, naturally.

Scott Disick's birthday celebration in Las Vegas continued Friday night with a party at one of his favorite haunts, 1Oak inside The Mirage Hotel & Casino. Disick was joined at the club by ex-girlfriend Kourtney Kardashian, Khloe Kardashian, Tyga and Malika Haqq.

Kourtney wore a gorgeous Versace leopard print green dress that showed off her long, toned legs and giant hoop earrings. Her sister Khloé was all smiles while posing in House of CB's Rivera latex dress and sky-high white heels.

The group hit up 1Oak around 1 a.m. to pose for photos and greet fans before setting up camp at the V.I.P. table. After enjoying the music from DJ Shift and Kid Conrad, Scott was presented with a black and white three-tiered Rolls-Royce themed cake. The group left the club at 3 a.m. after a night of sipping cocktails and taking photos with fans.

Though Kourtney and Scott broke up last July, the parents of Mason Disick, 6, and Reign Disick, 1, and daughter Penelope Disick, 3 remain close friends. The E! star even posted a cute throwback photo on Thursday to wish Disick a happy birthday.

"Happy birthday baby daddy!" she captioned the flashback photo of herself straddling Scott in a bikini while flipping the bird.

Scott's birthday weekend in Vegas will continue tonight with an appearance at Pool After Dark.
