Ashton joined Thomas to sing a cover of Garth Brooks' Friends In Low Places at the concert raising funds for Ashton's charity The Native Fund in Iowa City, Iowa last Saturday (27Aug16).

And the Die a Happy Man singer revealed the Hollywood star enjoyed their duet so much he wants to go on the road with him.

"He (Ashton) emailed me last night and said, 'Hey dude, I am going to go on the road full-time with you,'" Thomas told Entertainment Tonight at Tuesday's (30Aug16) 10th Annual Academy of Country Music Honors ceremony.

And it seems the pair may be making plans to perform regularly together as he added, "Maybe we can do a little tour together or something."

At the charity gig the duo belted out Garth's' 1990 hit while drinking beers in front of a delighted audience.

After the performance Thomas wrote on Twitter, "Thanks for helping me out @aplusk (Ashton's Twitter handle) your hometown crowd in Iowa City brought the heat!"

The Native Fund was set up by Ashton and American football star Dallas Clark to help their fellow Iowans. They were moved to create the fund after the film star's hometown of Cedar Rapids was devastated by floods in 2008.
