After the telecast, pretty much all the stars you’d ever imagine – and way, way more – headed from 30 Rock to the Plaza hotel for what has to be one of the most spectacular, star-studded after parties of all time. Some of the sights a guest might have taken in on the scene? Oh, just Bill Murray chatting with Martin Short and jangling a tambo. Nothing special, except the newly assembled, all-girl Ghostbusters cast, plus selfie opportunities with Beyoncé, Rihanna and Kanye West. (Seriously, though, check out current SNL cast member Leslie Jones’s Twitter – she got everyone.) Move along, it’s just Prince leading a jam session with Haim, Cuba Gooding Jr., Jimmy Fallon and a dirty-dancing Maya Rudolph. Also worth filing under “This Party Has the Greatest Music Ever”: Paul McCartney and Taylor Swift led a rendition of The Beatles’ “I Saw Her Standing There” that Late Night with Seth Meyers producer Mike Shoemaker dubbed “insane.” Then Swift launched into “Shake It Off.” Who’s that? It’s Martin Short creating the hottest new dance craze of 2015. https://instagram.com/p/zKEq0IIddA/ Have you ever imagined a world in which Kill Bill‘s O-Ren Ishii (Lucy Liu) and one of the Three Amigos (Steve Martin) hang out? Because it just happened. And once and for all proving this party was the nexus of the universe, MC Hammer was there (until 4 a.m.). So was Michael Bolton (sadly, no one has posted footage of him singing “Jack Sparrow”). Still want more? (You maniacs.) Per the party’s official release, the “lavish fête … drew big names early into Monday morning. Jay Z and Beyoncé hurried into the main ballroom to catch Sir Paul McCartney take to the stage at 1:30 a.m. for what turned out to be a series of surprise performances. The power couple congregated in a white leather booth toward the back of the room where they were joined by Justin Timberlake and Rihanna.” Down in New York City’s Chelsea neighborhood, the after-after party began swinging at No. 8 around 3 a.m. In attendance, loved-up couple Miley Cyrus and Patrick Schwarzenegger, plus current SNL cast member Aidy Bryant and veteran Horatio Sanz.
