Justin Timberlake

The 2015 CMA Awards were a HUGE night for a then-relatively unknown Chris Stapleton.

It was a truly epic performance.

A few candidates seem likely while one singer feels like an exciting long shot.

There are a number of country stars who enjoy a bit of marijuana every so often, or have at least tried it -- including some who may surprise you.

"It looks like an odd couple to most people, but we have a lot of the same influences ..."

If Stapleton DOESN'T show up onstage in Nashville with JT, did the show even happen?

Stapleton joined Timberlake for a special appearance at a Spotify event following the Brit Awards in London, England, on Wednesday (Feb. 21).

Did you catch their performance?

This duo is unstoppable!

It's groovy!
