The duo sang Loretta Lynn’s classic “Don’t Come Home a Drinkin”, trading verses while being backed by Clarkson’s house band.

Lynn passed away earlier this month at age 90, after a career lasting 60 years in which she won three Grammys and became a country superstar.

In the comments on YouTube, fans were shocked and impressed with Johnson’s performance.

“This is unexpected, didn’t know Dwayne sang until now and loved his low voice that matches with Kelly’s high notes which she killed it once more. What a great tribute to the late Loretta Lynn :)” wrote one viewer.

Another added, “His voice really actually fits that song. Who would have guessed Dwayne is a countryboy??”

Johnson has shown off his singing chops before, most notably with his role in the Disney movie “Moana”, for which he sang the fan favourite “You’re Welcome”.
