Ariana Grande

Ah, the relationship that defined 2018 (and the term "Big Dick Energy"). The couple-to-be first met all the way back in 2016, when Ariana made an appearance on Saturday Night Live. Fast forward to May 2018: both Pete and Ariana break up with their significant others (Cazzie David and Mac Miller, respectively). Then, on May 20th, they were spotted canoodling backstage at the Billboard Music Awards. What followed was a whirlwind romance, a ring after just a few weeks, countless matching tattoos, and even a song titled "Pete Davidson."
