Clarkson performed the song for her fans in celebration of Friday's release of several live covers on her website. The American Idol alum's collection includes covers of Coldplay's "Fix You," Florence and the Machine's "Shake It Out" and the Dixie Chicks' "Top of the Word," among others.
While her Rihanna cover isn't among the songs available for download on her website, Clarkson was sure to give RiRi props ahead of her Facebook Live performance.
"I just love this song, @rihanna kills it! #LoveOnTheBrain," she tweeted.
Check out Clarkson's stripped-down version of "Love on the Brain," accompanied by just an acoustic guitar and keyboard, below.
As for the ballad's original singer, she's got a lot of love for the song too.
Rihanna announced on Instagram earlier this week that "Love on the Brain" would be her next single with a little clip of a recent concert performance.
