Demi Lovato Tweets Photo Without Makeup

The 19-year-old singer-actress tweeted a barefaced photo of herself Saturday night. "No makeup," she wrote. "Goodnight xox"

In the shot, Lovato's hair is pulled back from her face and her perfect complexion glows without as much as a drop of foundation.

And while the former Disney star is clearly an attractive lady, she admits that she still struggles with her self- image.

"I'm not always perfectly happy with my body," she admitted in an interview with WE7. "After all, I'm a woman and what woman is? But I make sure I tell myself that I'm beautiful and I tell myself daily affirmations, so I would recommend that to younger girls—and guys."

"If you're struggling with self-image, you're not alone," she said. "It's something that I still struggle with today."
