Meghan Trainor's latest mirror selfie made Us look. Trainor, 31, took to her Instagram Story on Wednesday, October 29, to repost a photo taken by her coach, Bella Maher, and shared on Maher's personal training page, Malibu Bodies. In the snap, the women coordinated in all-black workout ensembles with white socks and sneakers as Trainor stretched out one leg to show off her long stems. She also held up her shirt to put her flat, toned abs on display and made duck lips at the mirror. "Progress. Power. Peace," Maher wrote over the photo.
