July 25 was one crazy Saturday. First, was the DJ being funny or was it just too soon? At 1:28 p.m., Diplo tweeted, “This is what happens when I DJ the pool,” with an Instagram link to a photo of the Cosmopolitan Bamboo Pool fire, less than an hour after the quick blaze was extinguished.

Later that night, things got hot again when Mirage’s 1 OAK hooked it up for Mariah Carey’s hosting gig, bringing the star singer a four-tiered butterfly cake topped with a gold tiara and tapping DJ Suss One to mix Mariah’s hits into the set. The scene was also decorated with the giant faces of Mimi and her beau James Packer, Australian mogul and developer of the shrouded-in-mystery Strip casino project Alon. NBA birthday boy DeAndre Jordan was in the house, too.

Meanwhile at Foxtail, Alien Ant Farm (Remember them? No?) paused their opening set for Hoobastank and P.O.D. (How about them? No?) during the Vegas Beer & Music Festival so frontman Dryden Mitchell could propose to his girlfriend. Beers by the pool ... anything can happen.

Finally, Joe Jonas’ DJ set at Hyde unsurprisingly included an appearance from his brother Nick Jonas for a special rendition of Nick’s hit “Jealous.” The crazy part: Afterwards they hung out with Cuba Gooding Jr. Oh, Vegas on a Saturday night. What won’t you do?
