Garth Brooks

A fan actually gave them the idea!

Yearwood and Brooks first met in 1987, before Brooks became a household name in country music.

As 2018 wraps up, The Boot is looking back at some of the best new music and biggest headlines of the year.

The final line of "Stronger Than Me" goes “I pray God takes me first ‘cause you’re stronger than me.” Yearwood tells ET it reflects a conversation she and Brooks have had before.

It'll be the first time anyone -- including Yearwood -- has heard the song.

He is actually a huge fan of the band.

The country music world has a lot of BFFs. No wonder the genre has so many great best friend songs.

The Hollywood Walk of Fame features everyone from actors to radio personalities, and there are plenty of Nashville names enshrined there.

Congratulations, graduates!

There's nothing quite like a live country music show ... but the next best thing might just be a live country music album.
