This season of America's Got Talent is proving to be one of the most competitive yet, and we're only three weeks in. In the midst of the audition rounds, there have been a couple of performers who left viewers wondering, "Haven't I seen you before?"    

Yes, you have. From Vine superstars Us The Duo to Voice Kids U.K. finalist Courtney Hadwin, some contestants are no strangers to the entertainment industry. See below for some previously famous America's Got Talent acts.    

Us The Duo
Husband-and-wife act Michael and Carissa Alvarado have seen quite some musical success since their Vine days. They were previously signed to Republic Records, opened for Pentatonix on tour and had headlining dates of their own across the country. They have 1.2 million monthly Spotify users, which had Twitter wondering why they were auditioning for a competition show to be discovered when they're already famous.     

Noah Guthrie
Glee fans will recognize the 24-year-old as Roderick Meeks on the sixth and final season of the hit series. He is clearly ready to take the next step in his career, absolutely slaying a cover of Rihanna's "Love On The Brain" for his audition.

Courtney Hadwin
​This 13-year-old girl from England shocked the judges (and won the golden buzzer) with her wild, soulful performance of Otis Redding's "Hard to Handle." But Hadwin is a singing competition veteran. She was a finalist on The Voice Kids U.K. in 2017, ultimately losing to fellow contestant Jess Folley.

Samuel Comroe
​Comroe had the crowd in hysterics during his audition. The comedian, who suffers from Tourette syndrome, has shown his face on television screens before. He appeared on a few episodes of The Real Husbands of Hollywood, starring Kevin Hart. He also appeared on Conan as a comedic guest.
