Demi Lovato was more than happy to lend her musical talent and star power to President Joe Biden and Vice President Kamala Harris' TV special, on Wednesday, Inauguration Day. The 28-year-old singer rocked her short pixie haircut with a beige power suit as she beautifully belted out «Lovely Day» from Los Angeles. Lovato's performance also incorporated famous faces like Lin-Manuel Miranda and many health and essential workers.
