There was plenty to keep up with at Sunday night's (Nov. 24) 2019 American Music Awards -- from Selena Gomez's show-opening performance to Taylor Swift's artist of the decade spectacle -- but there was also a lot going on behind the scenes that you might have missed.

Thankfully, Billboard had you covered backstage at the show and on the red carpet, and you can follow along with our night, minute-by-minute, below (all times PT).

4:33 p.m. PT: No better way to get our AMAs night started than with the first celeb spotting of the night: Shawn Mendes is chilling with his team at the end of the red carpet before the madness of the night truly begins.

5 p.m. PT: The show gets under way with Gomez's double-dose performance of "Lose You to Love Me" and "Look at Her Now" -- but the press room is having a hard time hearing anything with the volume turned way down on the monitors. Thankfully, the sound gets turned up for the very end of Gomez's triumphant return to the stage.

6:49 p.m.: One of the biggest winners of the night so far, Billie Eilish, makes her way backstage to pose for photographers with her very first AMAs, for favorite new artist and favorite artist – alternative rock. She rocked a lot of different outfits throughout the night, but for her photos, she's back in the same head-to-toe Burberry outfit she wore on the pre-show red carpet.

6:53 p.m.: Billboard News' own Tetris Kelly has great timing: As he makes his way out of the backstage bathrooms, Swift and her dancers are on their way to the stage for her career-spanning artist of the decade performance. Kelly hollers, "Slay, Taylor!" at the crew, and Swift looks back and gives a wave.

7:37 p.m.: Fans had to settle for a nose kiss onstage during Mendes and Camila Cabello's steamy "Señorita" performance, and backstage they graduated… to a forehead kiss. The duo teased photographers for a second with the possibility of a lip-lock before Mendes planted a sweet smooch on her forehead instead. His adorable smile more than makes up for the near-kiss.

7:57 p.m.: Lil Nas X is clearly loving his very first American Music Award, holding it up to his cheek lovingly and cradling it like a newborn baby as he takes pictures backstage. And he's the last celeb to make his way across the step-and-repeat for the night.
