'Let It Go' superstar Demi Lovato has lent her support to pop sensation Ke$ha, who is currently seeking treatment for an eating disorder at the same rehabilitation centre she once spent time at. 

Ke$ha is at the Timberline Knolls Centre, which is set in 43-acres near to Chicago, and Lovato admitted herself to the same facility three years ago for bulimia and bipolar disorder.

Speaking to an interviewer at a pre-GRAMMYs event recently, Lovato explained that she's in the best hands and hopes that Ke$ha gets a lot out of the experience: "Yeah, I wish her the absolute best and I think she is doing a really great thing for herself."

"It's really great when you take time out of a schedule that everybody wants you. There are so many things, you work so hard and then you kind of forget about yourself, and you don't really get to treat the things that everyone has... like stress."

"When I took that experience, I needed it to live. It taught me a lot and it helped me a ton. I wish her the absolute best. She's a sweet girl and she's going to be fine."
