7. Demi Lovato
The 25 year-old Sorry Not Sorry vocalist absolutely killed it in her performance at the American Music Awards on Sunday night. Demi has made a point of discussing the highs and lows of her career, but lucky for her, 2017 has been an exceptional year for the star.
Overall, the 2017 American Music Awards made for a memorable night. Powerhouse performances by Christina Aguilera, as well as Pink and Kelly Clarkson were among just some of the highlights of the night.
