OTRC: Demi Lovato returns to rehab, calls cutting scars 'beautiful battle wounds'

Demi Lovato returned to Timberline Knolls, the rehab facility where she sought treatment in 2010, this time as a speaker.

"Today I went back to the treatment center I went to last year, to speak to the beautiful women fighting their inner demons... was so honored," the 19-year-old former Disney star wrote on Twitter on December 4. "To be able to share my story and let them know that it gets easier. Life is beautiful... You are worthy of it."

Lovato also opened up about her struggles in the January issue of Glamour magazine and said she felt like her self-harm scars and the tattoos on top of them are beautiful.

"I think scars are like battle wounds -- beautiful, in a way," Lovato told Glamour. "They show what you've been through and how strong you are for coming out of it. My tattoos say 'Stay strong.' 'Stay' on one [wrist] and 'strong' on the other. Now I'm able to look at them and be thankful for being alive. I think that I've been blessed over the past year to be able to start over."

Lovato entered treatment about a year ago for "emotional and psychical issues." She later revealed that she battled anorexia and bulimia.

On April 19, a Disney Channel spokesperson confirmed Lovato would not return to her show "Sonny With a Chance." The actress, who had played main character Sonny Munroe since the show began in 2009, had said she wanted to focus on her music and that she didn't think shooting the series would be "healthy" for her recovery.

Lovato recently revealed that she has struggled with food addiction, cutting and depression and told Seventeen magazine: "I basically had a nervous breakdown."

The singer said that her stint in treatment helped her to distill her true friendships and mill out the "artificial ones," who she addresses in her recent single, "Skyscraper."

"It's to every person who tried to bring me down. Everyone has the bully or the mean girl or the ex-boyfriend who tried to bring them down," Lovato told Glamour. "For me, I think of the people who really weren't there for me when I went into treatment. It was a really dark time for me because I had only a few people -- I had surrounded myself with so many artificial friendships. It's about those people too."

Lovato was recently linked to her ex-boyfriend, former "That 70s Show" star Wilmer Valderrama. The two were spotted kissing in Los Angeles on November 1, according to People magazine, which posted a photo of what appears to be the two making out.

Lovato was previously linked to the 30-year-old actor in 2010, shortly after her split from Joe Jonas.

Lovato also opened up about to Glamour about her requirements in a boyfriend, saying that she needs, "Someone who's not only supportive in my career but also in my recovery. It's a big responsibility dating me. Because I come with a little bit of baggage, you know? I'm completely open. I'm honest about the journey I've been on, so I definitely don't take dating lightly anymore. And they have to make me laugh."

Lovato also explained the meaning of her "Skyscraper" lyrics, "You never really can fix a heart."

"I think every time you get your heart broken, there's a little piece of it that chips away, and I don't think you ever get that piece back," Lovato continued. "But I think you're able to bandage it with time and with new people and other things that make you happy."

Lovato's latest album "Unbroken" was released on September 20 and marked her third studio album.
