Demi Lovato [1]'s appearance at Glamour's Women of the Year Awards in Los Angeles [2] was one for the books. Just hours after seemingly confirming her relationship with UFC fighter Luke Rockhold [3] by stepping out hand in hand with him in New York City, then posting a photo of the outing on Instagram [4], the singer stepped out sans her new boyfriend to attend and perform at the powerful awards.

Wearing a sheer and structured printed dress, Demi walked the red carpet before changing into a fitted off-the-shoulder LBD featuring a large buckle belt to perform an emotional rendition of her hit "Skyscraper" that left the crowd, including Keke Palmer who posted a video of her reaction on Snapchat [5], moved. Scroll ahead for more photos of Demi's night and to find a short clip of her performance.
