Madison Elle Beer is like any 21-year-old. She loves a New York slice—”there’s nothing in L.A. that compares” and cartoons—she has a “Nightosphere” tattoo on her foot, a reference to Adventure Time, and she included a Rick and Morty snippet in “Homesick,” a track from her debut musical album Life Support. She also has 23.6 million followers on Instagram. Ever since Justin Bieber posted a link to one of her YouTube covers at the age of 12, leading to a record deal at 13, she’s been under a constant, ever-bright spotlight, observed as she makes moves to become the pop star she’s always dreamt of becoming. With Life Support, an emotionally resonant pop album for an internet-addled generation, Beer proves that she can, in fact, turn her wildest dreams into reality. It’s her out-of-this-world ambition that led to the singer’s rather unexpected friendship with Justin Roiland, the co-creator of Adult Swim’s Rick and Morty, on which he voices both titular characters, and the co-creator of Hulu’s Solar Opposites. Below, Roiland joins Beer from another universe to talk about his own contribution to her album, The Eric Andre Show, and being Madison Beer.
