Machine Gun Kelly is getting candid about his mental health.

Speaking to Drew Barrymore — as he painted her nails — on her talk show, the 31-year-old musician shared how he's become more emotionally honest and vulnerable outside of his music.

"I think I'm new to being vulnerable outside of songs. I see a lot of pictures of me and there's like, smiles on them," he said. "It's just weird though because I didn't feel good at all that day and I kind of am sick of smiling on days when I don't feel like smiling."
