Teddy Swims Performs 'Mr. Know It All' at 2026 AMAs
teddy swims brought Mr. Know It All to the American Music Awards on Sunday night. He sang it on a stage built like a boarded-up house, turning a recent single into a live-TV showcase at Las Vegas’ MGM Grand Garden Arena.
Mariah the Scientist Introduced Swims
Mariah the Scientist, a fellow Georgian, introduced him before the performance. Backed by plucky guitar and hand drums, Swims sang about anticipating the demise of a relationship, which fit the song’s bruised edge more than a glossy awards-show treatment would have.
Swims gave the song its live debut at Coachella in April, where he played both weekends and closed his set with Lose Control. That run also included guest appearances by David Lee Roth, Joe Jonas, and Vanessa Carlton, which helped turn the festival sets into a larger promotional push rather than a one-song stop.
2025 Album Still in Play
Swims released his most recent album, 2025’s I’ve Tried Everything but Therapy (Part 2), more than a year before this performance. He has stayed visible with singles like Gone Gone Gone, which features David Guetta and Tones and I, and that track is up for Collaboration of the Year at this year’s AMAs.
He also contributed You’ve Got Another Thing Coming to the soundtrack of the second season of Nobody Wants This. That mix of festival sets, soundtrack work, and awards-show airtime gives the performance a clear business purpose: keep the catalog moving while the newer single cycle is still active.
Las Vegas Nominations
The 2026 AMAs were hosted by Queen Latifah, with Taylor Swift leading the night with eight nominations. Sabrina Carpenter, Morgan Wallen, Olivia Dean, and Sombr each had seven, so Swims’ slot came inside a crowded show built around nominated hits rather than a single headliner.
For Swims, the better read is simple: Mr. Know It All is being treated as part of a larger rollout, not a one-off TV performance. The live debut at Coachella and the AMAs appearance put the song in front of two very different audiences, which is the kind of exposure labels still want when a campaign has to stretch beyond one release cycle.
