Grace VanderWaal performed her new "Moonlight" single on her old stomping grounds—the America's Got Talent stage. The 13-year-old won the 11th season and, well, graced the competition show with her commanding presence.

The singer strutted around the stage with confidence as she performed the dance-y tune with her trusty ukulele while the audience clapped along. The foggy setting, complete with a bright moon, made the performance all the more special. Judges Simon Cowell, Howie Mandel, Mel B and Heidi Klum welcomed her return with a standing ovation.

VanderWaal is currently working on her debut full-length album, which will be the follow-up to last November's Perfectly Imperfect EP. She plans to embark on the Just The Beginning Tour—her first headlining trek—this fall. It kicks off in Los Angeles on Nov. 5 and wraps up on Feb. 23 in Seattle. Tickets are now available on the singer's official website.
