Trainor: "When I got famous, all of a sudden guys wouldn't look at me. Period. So I felt a little sad, a little frustrated. Like, What's going on here? I've never been prettier in my life and I'm so cool and successful."

Trainor: "I went from being a casual songwriter who wore big sweatshirts and leggings every day to someone telling me I was going to be a pop star who's on camera every day. I didn't know a lot about fashion because I had kind of given up on my relationship with clothes. Now, I have a stylist that's shown me the right places I can show off my body - but I still stick to my comfort zone in fittings. I want to be covered and I think I can be sexy fully covered. That learning process has been helping me with my confidence. And I follow actresses and singers who post on social media about being confident."

Trainor: "I don't consider myself a feminist, but I'm down for my first opportunity to say something to the world to be so meaningful. If you asked me, 'What do you want to say?' it would be, 'Love yourself more.'"

Trainor: "I want to be better at being single, and I want to be better at feeling okay about being single. I don't need a boyfriend."

Trainor: "Owning your curves means being confident - actually being confident - in your own skin. Growing up was tricky for me, it was so hard to shop with all of my friends and not being able to fit into the tiny clothes they were wearing."

Trainor: "As the CEO running my life, running Meghan Trainor, I have to say 'no' to things all the time, and it's been very uncomfortable and very difficult. I've said 'no' and it's actually worked - even when I never thought it would work."

Trainor: "I tried to go anorexic for a good three hours. I ate ice and celery, but that’s not even anorexic. And I quit. I was like, 'Ma, can you make me a sandwich? Like, immediately.'"

Trainor: "There's a lot of power in the word 'no,' and a lot of people, like myself, need to know that."

Trainor: "My team of people around me, they were like, 'Don't be waiting and begging for a man.' You know what I'm saying? Like, 'Don't be desperate because you think having a boyfriend is going to be better. It might be harder with your career.' And then I was like, 'Yeah, you're right. I need to enjoy this.'"

[On how she felt about winning a Grammy]

Trainor: "It still hasn't kicked in yet. I haven't had a second to think about it. And I don't physically have the Grammy! So I can't even look at it!"

Trainor: "Ricky's [Reed] a lot like me. He always says we have the same brain. He does all different genres, and it just happens his first big hit as a producer was [Derulo's] "Talk Dirty to Me," and that Pitbull is his best friend. But he can actually - I swear - he can do every genre."
