“Got 5 miles in with my favorite runner, Ivey Childers,” Carrie Underwood, 37, captioned a selfie she uploaded to her Instagram Stories on June 3. The country music superstar joined Ivey — a “recipe developer and creator of the popular cupcake and cake boutique bakery, Ivey Cake,” per her website – to celebrate Global Running Day. What Carrie should be celebrating is Make-up Free Selfie Day, because the picture she posted to the ‘gram was gorgeous.
