We all know Diddy knows how to party and his sons are no different. Justin and Christian Combs made their father proud on Sunday night (Oct. 30) as the moguls in the making hosted the The Purge, the second annual Tonite Halloween Bash in Hollywood, Calif. In true Combs fashion, it was a night to remember, complete with Ciroc flowing, Harlem shaking, Bad Boy hits in rotation and special performances from 21 Savage, Chris Brown, Casey Veggies, Lajan Slim, Justin and King Combs and the whole CYN crew.

The invite-only event went down at Taglyan Culture Complex, a banquet hall large enough to host the hundreds of guests who began arriving via shuttle buses -- arranged by the venue to keep the location secret -- promptly at 9 p.m. The Halloween theme was in full effect with an imperfect balance of creative, safe for trick-or-treating with the family and barely-there lingerie costumes -- yes, thongs are now costumes.

By midnight the venue was packed from wall to wall, but still no sign of the hosts. Word on the security walkie talkie was that unruly fans who discovered the location swarmed the gates and jumped on Christian's Jeep in attempts to crash the party. Security fired off the pepper spray and fire marshals threatened to shut it down, but the show went on. Finally, at around 1 a.m., Christian, dressed as Cam'ron in a pink fur and matching hat, mobbed the stage with his SNL and CYN crew.

The first special guest of the night was Def Jam's own Lajan Slim, who grabbed the mic and turned up to his hit "Haitians." The Broward County native and King Combs were soon joined by Justin, who emerged shirtless, with his hair died green and face painted like the Joker.

Then it was time to go Savage Mode. A quick DJ switch and 21 Savage was up next with his Metro Boomin-produced hit "No Heart." It seemed like everyone in the room dabbed or two stepped on command as 21 performed the track. The stage was already flooded and the energy only got more intense with the bass drop of the crowd favorite, "X" featuring Future. "Aye! I'm just stuntin' on my ex bitch," the entire room rang out.

With Savage wrapping up, Young Thug -- who was originally slated to perform -- was supposed close out the night. As DJ Jae Murphy kept the hits coming, it was clear Thugga wasn't going to make it. Good thing Chris Brown was on deck to save the day. From his VIP section, a Breezy, who showed up to the party without a costume, got on the mic and belted out his Solo Lucci-assisted single "Wrist," followed by his club banger "Loyal." Cassie Veggies wasn't too far away and he jumped on the mic to spit a few bars of his track "Backflip."

A few more bangers from Young M.A and throwback Juvenile were played and then it was lights on, party done -- or 2 a.m. if you've ever partied in L.A. Although Jeffery never made it to perform, Justin and Christian put on a hell of a party. Diddy was even spotted in VIP dressed in a Mortal Kombat-inspired look doing his signature dance moves. Take that.
