Is that Kelsea Ballerini... or a Victoria’s Secret model?! It was hard to tell the difference as the country singer took the stage alongside The Chainsmokers for a performance of their hit “This Feeling” during the VS Fashion Show on Dec. 2! The trio belted out the track during the Golden Angel segment of the show, which featured models like Candice Swanepoel, Stella Maxwell, Jasmine Tookes and more strutting down the runway. Kelsea fit the theme, too, as she showed off her insanely toned legs in a teeny, sparkling mini dress. GORGEOUS!
