Lauv opened the song to the backdrop of couples making out on the park-themed stage. Sivan then entered to flawlessly sing the track's second verse, before melding his voice with Lauv's for the song's catchy chorus.
"I'm So Tired" is Lauv's first duet since his 2018 track "There's No Way" with Julia Michaels. Lauv and Sivan's track also debute at No. 86 on the Hot 100 this week.
