The Nashville crowd was already going nuts at Friday's Justin Timberlake concert when the singer busted into the beloved Garth Brooks song Friends in Low Places.
Then Brooks strolled out to sing with Timberlake. Nuts turned to pure pandemonium.
Some 50,000 people singing along to every word, Timberlake strumming along with a big ole goofy grin, Brooks hamming it up and shooting selfies onstage, Santa Claus, unicorns, rainbows. It all happened during the rowdy number captured by fans.
Garth was so wowed that he posted a selfie-made video of Timberlake on Instagram: "I saw an ENTERTAINER tonight!@justintimberlake #Justinrcredible"
