Nick Cannon led a sweaty crowd through two sweltering Miami nights at the iHeartRadio Ultimate Pool Party this weekend at the Fontainebleau Hotel, featuring performances from Jennifer Lopez, Ariana Grande, Iggy Azalea, Lil Jon, Neon Trees, Magic!, and Tiësto. If you missed all the DJ cameos and crunk dances during Yahoo Screen's livestream, here were the biggest moments of the splashy soiree:
J.Lo Danced Again and Again. Jennifer drove her show with so much force, not even a banged-up knee could stop the 44-year-old diva. After asking the crowd, "Can we take it back to the J.Lo days for a minute?" she lunged into a modernized rendition of her 2001 hit with Ja Rule, "I'm Real." A literal lunge by the "On the Floor" singer onto the floor during this number resulted in what looked like a nasty knee scrape; video cameras on the scene cut away quickly at J.Lo's dramatic knee-drop moment, but fans in the audience couldn't help but notice that the singer's left leg started bleeding shortly thereafter.
Anyway, don't worry: J.Lo didn't miss a beat and kept on going, and later that night, she tweeted a photo featuring her smiling face and scraped knee, ensured concerned fan that she was fine, and included the hashtag "#stilldoingthekneedroptomorrownight." The woman's a pro!
Jenny Brought the "Block"-Rockin' Beats. After booty-popping to bits of new tracks off her latest album, A.K.A., J.Lo said she just couldn't leave without doing "Jenny From the Block," of course. Some partygoers may have actually been too young to know the words to Jenny's homegirl anthem, but her funky break at the end of the song got everyone dancing, Bronx-style.
Ariana Grande Had No "Problem" Showing Some Hometown Love. The tiny powerhouse vocalist reminded the audience that she's from South Florida too, and rocked thigh-high, platform-heeled go-go boots during a dance routine through which she sang live flawlessly.
Tyler Glenn Was Dancing With a Friend. Speaking of dancing, one of the world's most famous DJs, Tiësto, was joined by Neon Trees frontman Tyler Glenn, who busted out some of his own dynamite disco moves — while wearing a very neon '70s shirt — to accompany his performance of "Red Lights." Later, Tiësto was joined by rising singer-songwriter Matthew Koma for another surprise collaboration, "Wasted."
Iggy Azalea Worked It. While performing her single "Work," the Aussie — who first lived in Miami when she relocated to the States in 2010 — took a cue from Ariana and threw some love to her former hometown of sorts, rapping: "No money, no family/16 in the middle of Miami." Iggy also had some pretty fancy dance moves.
Nick Cannon Showed He's Got Talent. Yes, Mr. Carey spent most of the weekend dancing and screaming shirtless in the crowd, but he reminded everyone that he makes music, too. And he couldn't have done it in a more appropriate city, teasing some of his new single "America," featuring Miami's own Pitbull.
