2015ish rock song with a South USA vibe, something about being a bad man, slow song by a band known for heavier metal

I remember the main singer was male with a deep voice, but part way through a female singer had a few verses, she had a country twang (and an awesome voice). Pretty sure there was a harmonized duet on the chorus towards the end. I recall it was a slow song, but the band was known for being more heavy metal (I hadn't heard of them when I looked it up years ago). I feel like the chorus went along the lines of "I'm a bad man, that's what I am" but I can't find it. I've been through my YouTube history, but to no avail. Not a lot to go on, I know...
