Kelsea Ballerini looked like a bit of springtime, as she stepped out in an adorable white mini dress for a concert in Miami Beach on Wednesday (March 16). The country music star, 28, was the center of attention at an Aerie benefit promoting positivity across social media, where she debuted a new song called “Keepin’ It Real,” written exclusively for the clothing company’s star-studded event, per their website.
