Ariana Grande and Little Big Town's Karen Fairchild perform during the 48th annual CMA Awards at the Bridgestone Arena on November 5, 2014 in Nashville, Tennessee. 

Wearing neon-lined outfits straight out of the virtual world of TRON, Little Big Town took the stage at the 2014 CMA Awards to deliver a rousing version of "Day Drinking," a performance immediately followed by Ariana Grande singing her Nicki Minaj/Jessie J collabo "Bang Bang." 

But since Minaj and Jessie weren't at the CMA Awards, Little Big Town pitched in on the "Bang Bang" vocals. Incidentally, Grande also wore a color-changing neon outfit, although hers was more Jem & the Holograms than TRON. (FYI, Katy Perry rocked a similar outfit in the past.)

Even though we knew Grande would be there, we weren't expecting her performance to be so straight-up pop. It was a weird moment -- especially for an ostensibly country awards show -- but it was definitely memorable.

Earlier that evening, Meghan Trainor and Miranda Lambert provided another pop crossover moment by performing a countrified version of "All About That Bass" (which Brad Paisley pointed out should have been altered to be about the bass fish, given the country setting).
