'No' songstress Meghan Trainor has opened up about the advice she would give her teenage self if she could go back in time. 

During a new interview with Seventeen magazine, the beauty spoke about her growing body confidence:

"A couple of years ago, you'd never see me in a dress. And now I want to sha-zoom me. I mean, I want it tight. I want to show off what I got!"

She went onto add that when she was in her teen years, she would go out of her way to hide any parts of her body that were on show: "For a good six years, I wore sweatpants and sweatshirts, even on vacation in 90-degree weather—I was hiding. In pictures, you can just see my face, like 'Help.'"

When asked what she would tell her 17-year-old self, Trainor explained: "I want to hug that girl. I want to tell her, 'You're okay.'"
