Looking good, Gabourey Sidibe!

"I used to hate mirror selfies. Now I do them every day. I'm just too black and fine! I can't help it!" she candidly captioned the image.

Her fans totally agree and made their thoughts known in the comments section.

"Yes you are, get it boo!" one user wrote.

"My first diet started when I was six-years-old. I've never been a small girl," she revealed. "One day, I had to sit down with myself and decided that I loved myself no matter what my body looked like and what other people thought about my body. I got tired of feeling bad all the time. I got tired of hating myself."

She also shared her advice for younger girls when she appeared on Watch What Happens Live in September, when a fan called in and explained how her daughter was being bullied at her junior high school.

“Junior high school is a battlefield. Get her in a class or something. Have her find something that she loves about herself. As long as she builds herself and she finds her own self-love, no matter what anybody says about her, it’ll hit her and fall off her,” the actress shared. “Junior high school sucked for me. High school sucked for me. I didn’t get good with myself until I was like, 25 years old. Tell her to hold strong. Tell her to hold on, but it’ll be worth it, honestly.”
