Demi Lovato, who embraced her issues and embarked on a campaign trail to help others facing similar addiction and self-harm issues after leaving rehab in 2010, has Kesha's back.

Pop's dirty girl entered rehab to treat an eating disorder this weekend, and Lovato has already reached out.

Kesha is reportedly staying at Timberline Knolls, the same facility outside of Chicago in which Lovato sought treatment.

A source claims that Lovato wants Kesha to eventually join her in her quest to support and speak out to those with similar issues. She reportedly would like Kesha to be a celebrity spokesperson for eating disorders.

While it's a bit too soon for Kesha to be thinking of all that, since she only just began a 30-day treatment program, she could certainly be a force with Lovato once she completes her course of rehab. Lovatics and Warriors would love to see the ladies open their arms even more. Given their sphere of influence, they could change the world for many of their fans.

But more importantly, having Lovato's support is essential for Kesha. She's been there. She's done that. She wrote a best-selling book.
