Demi Lovato feels her most beautiful when she's wearing no make-up.The 28-year-old singer appeared on The Drew Barrymore Show as part of the show's Beauty Week, and she confessed that barefaced beauty is her favourite look. "I think I feel the most beautiful when I have a bare face, even in my sweatpants, just hanging out with my friends. I don't know, that's just when I feel the most like myself. (Just) clean and comfy," Demi shared. She also opened up on her decision to cut off her locks, after surprising fans with her hair transformation late last year. "I'm doing what I need to do for myself and my well-being. I'm putting myself first in front of my career, and that's something I had never done before. I was so preoccupied with being the sexy, feminine pop star that I just ignored who I am," the Sorry Not Sorry hitmaker shared, noting that she wanted to be free from her past. "I cut my hair because I just wanted to free myself from all the gender and sexuality norms that were placed on me as a Christian from the South. And when I cut my hair, I felt so liberated. I wasn't subscribing to an ideal placed upon me to be someone that I'm not," Demi explained, before adding that she's the "happiest I've ever felt and that's because I'm being honest."
