It's the fourth single she's released off her upcoming 'Rockstar' album.

Track featuring the late Lynyrd Skynyrd singer appears on her upcoming album, 'Rockstar.'

Tracks are from country legend's guest-packed rock album 'Rockstar.'

"I hope it is something that will touch you and maybe touch enough people to want to make a change for the better," country star says.

Guests include two surviving Beatles, Steve Perry, Rob Halford, Ann Wilson and two late Lynyrd Skynyrd members, among many others.

Guitarist explains how he ended up on two 'Rockstar' tracks.

Country legend's star-studded LP will arrive this fall.
