Demi Lovato On Why She's Single: "I Really Need To Focus On Myself"

Demi Lovato covers the November issue of Teen Vogue, and the 20-year-old starlet chats about everything from her latest gig to her love life.

On looking up to her X Factor co-star Britney Spears, Demi tells the mag, "[S]he was one of the first concerts I ever went to. She's incredible. She's such an icon that I didn't know what to expect, but I was excited to find out that she's really sweet and funny and quirky. We have so much fun. We're the two girls on the show, so we're always laughing together, and we kind of have each other's backs."

Speaking of people having her back, Demi also talked about how she's had to cut certain people out of her life. "I did kind of a friend cleanse right after rehab, where I weeded out people who didn't have my best interests at heart," she says. "Now I have friends who love me for who I am and don't care about what I'm doing. Most of them aren't in the industry. Some of them don't even know my songs!"

"Obviously, I sleep, eat right, exercise, and meditate," she says when asked about how she's staying healthy and happy. "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."

When asked about rumors that she's dating Niall Horan, Demi replies, “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.”
