three years ago. My, my, my, how the world has changed! But one thing apparently hasn't changed: the model, TV host, and social media mayor's love for hair accessories. For those who don't remember: In the summer of 2018, Teigen started documenting each headband she wore to work out, sharing not only videos of her look but a theme song for the ever-changing hair accessory. Husband John Legend whipped up the little ditty, which goes, "Headband of the day/ It's the headband of the day/ Push your locks away/ It's the headband of the day." No wonder he became an EGOT winner shortly after!Â
