Brittany Mahomes is lassoing in a new decade with plenty of style. "Feeling 30 today," Mahomes wrote via her Instagram Stories on Sunday, August 31, sharing a pic from her Nashville birthday bash the evening prior. Mahomes went full country, matching Music City's locale, and rocked a cropped denim jacket, matching cutoff shorts and a white T-shirt. Of course, no true country girl could forget a cowboy hat and boots - the KC Current co-owner chose a brown hat with studded trim and metallic silver boots to complete her ever-chic 'fit.
