Justin Timberlake and Chris Stapleton brought the house down with an epic country duet at Nashville's Bridgestone Arena on Wednesday night, and the "Mirrors" singer took to Instagram on Thursday to rave about his friend and fellow musician.

"About last night... I've been friends with @castapleton and his lovely wife Morgane for a couple of years now, but sometimes you meet people and feel like you've known them your whole life," Timberlake captioned a shot of him and Stapleton after their duet. "He is one of THE MOST gifted musicians, songwriters, and vocalists I've ever met. So stoked to share this moment with him and watch him put the WHOLE WORLD on notice."
