The event took place at Vegas' 1Oak Nightclub and proved to be just as fluffy as we all expected.
Mariah kicked off the spectacle, unsurprisingly, with a walk on the red carpet plus a complete photo op. But the real fun started inside the after-hours venue when Carey made her anticipated DJ set.
DJ Suss One started off spinning on the decks as Mariah showed off her DJ skills by taking off her leather jacket, recording Instagram videos, drinking cocktails and avoiding the CDJs and mixer all night.
