Watch Dolly Parton Perform With Australian Christian Rock Duo in New Music Video (Exclusive)

It's Dolly Parton like you've never seen her before!

It's Dolly Parton like you've never seen her before! 

The legendary singer teamed up with Australian Christian rock duo For King & Country on a remix of their song, "God Only Knows," and only ET has the exclusive behind-the-scenes video. 

"This song was Heaven-sent," Parton says in the clip. "I wanted to be a part of it because it just speaks to so many people out there that are having a hard time going through rough times."

To illustrate that message of redemption, Parton pulled double duty in the music video; she starred as herself and and as a prostitute, complete with fishnet stockings and a gold mini-skirt.     

The music video came together after For King & Country's Joel and Luke Smallbone reached out to Parton hoping she'd sing on a remix of the song, which they released earlier this year. The deal was sealed over Skype, when she was in Nashville and they were in Los Angeles. 

"It's a beautiful song and I love singin' it with them," Parton tells ET. "I think we need this song this day and time." 

The video for "God Only Knows" premieres tonight.
