Thomas Rhett is showing off his souful side with a cover of Bruno Mars’ ballad, “When I Was Your Man.” A video of the performance has been posted at RollingStone.com just as Thomas comes off his first weekend of shows opening Florida Georgia Line’s Anything Goes tour. Thomas also covers Bruno Mars and Mark Ronson’s “Uptown Funk” for his finale.

He says, “I’m obsessed with Bruno Mars’ records. I’d give my right leg to be able to sing like that dude.”

Watch for a CMT special where Rhett and Mars collaborate. I'll bet you it happens soon.
