Demi Lovato has been through a lot this past year, including rehab due to eating disorders and cutting issues, and she says her friendships have really helped her get though this difficult time.
It's a well-known fact that she and Selena Gomez are BFF's, but she told Billboard that she also counts Kim Kardashian as a close friend.
"I feel like there are some people that you're friends with that talk to you on Twitter or you text, but the people that are really there for me are the people that were there for me when I went into treatment," Lovato says. "The people that were calling me while I was in there were Kim Kardashian and Selena Gomez. Those two girls, they meant the world to me. They still do."
Kardashian tweeted her support of Lovato's album, writing, "My lil sis @ddlovato's album comes out today!!! I just got UNBROKEN! Go out & get it! Its sooo good! So proud of u Dem! Xo"
Lovato's Unbroken album has done well as her Skyscraper single shot to the top of the charts. "I took a long time on this album, and I've been on such a journey over the past year that it just feels awesome to be able to release music that I've worked really hard on, and now that it's done well [on the chart] it feels even better," she says.
