demi lovato niall horan teen vogue Demi Lovato on Niall Horan, therapy and putting recovery first in Teen VogueDemi Lovato is just 20 years old, but she’s already topping the music charts and mentoring singers on “The X Factor.” She tells Teen Vogue that it’s a bit unbelievable at times.

“The amount of success that I’ve had, even just in the last six months, is incredible to me,” Demi says.

Teen Vogue: Did you hesitate at all when Simon offered you the chance to join The X Factor? Or were you just totally psyched to do it?

Lovato: It was a no-brainer! Right before I got the offer, I’d been sitting in a meeting feeling really discouraged [about my career], wishing I was further along. And I decided that I needed to stop thinking about what I wished I had and start thinking about what I was going to have. I was ready to do something new, and I wanted to put that out there, in the universe . . . and then he called, literally, a week and a half later.

TV: You’re a little young to be a mentor. What kind of advice are you going to give your team?

DL: There’s so much more to it than just being a talented singer. I’m going to help them mentally prepare for everything that’s coming–like, all these things that have happened to me recently, I really attribute them, in part, to the work that I’ve been doing on myself. The second that I became more centered and aware of who I am, my performances got better, and I was better able to relate to people. For a long time, I was pretending to be someone that I wasn’t, and I was miserable. When I came out and said, “I’m human, I’ve got problems, but I’m willing to share them,” that’s when I started to really connect. I’ve just begun working on my fourth album, and I want to do that in my music too. I’m tired of songs that don’t have much emotion in them.

TV: Two years ago, you left a tour and checked yourself into rehab. What are you doing now to ensure that you stay healthy?

DL: Obviously, I sleep, eat right, exercise, and meditate. And even when I’m filming or touring, I keep up my daily routine. I know that I can’t miss my therapy appointments or things will get a little rocky, so I always put my recovery first.

TV: And yet you’ve still got some friends in the business. For example, there’s no shortage of rumors about you and Niall Horan from One Direction.

DL: He’s a really awesome, sweet guy. But he’s not my boyfriend…. I’m in a place right now where I really need to focus on myself. Obviously, I’m still going to like people–or love them–but I need to not be in a relationship for a while because I need to be okay with being alone, first. I’m really happy right now. I never thought it was possible to be happy because of how depressed I was my entire life. But I feel so incredible. It’s like I’m living in a dream.
