Just after the new year, Ke$ha checked into a rehab center to deal with an eating disorder, reportedly brought on by her producer's criticism. Now she is reaching out to her fans to thank them for their support during this difficult period of her life.

The pop star likely has limited communication within the facility, so she asked a good friend to pass a few messages along to her fans. Tweets sent out from Ke$ha's account explain the situation.

This is Kesha's friend. She asked me to tweet an update for her because she doesn't have access to twitter right now — kesha (@KeshaRose) January 21, 2014

Ke$ha's friend added a few more updates from the "Die Young" songstress:

she says "THANK YOU. SOOO MUCH. I'm overwhelmed to tears by all of the love, letters, and support!! I'll be back soon and better than ever — kesha (@KeshaRose) January 21, 2014

ohhh and she can't believe Timber is still number one! "Fck YEAH animals! PARTY ON!!!!" — kesha (@KeshaRose) January 21, 2014

Fans and animals alike can now sleep well knowing that Ke$ha is getting all of their encouragement -- unless they're brainstorming ways to fulfill her next request. It's an odd one.

The singer's friend sent one more tweet 10 hours later asking fans to donate a certain body part to Ke$ha's latest art project.

Hey guys this is K's friend again. She's doing well and needs more of your teeth to make art with at the treatment center. She misses you :) — kesha (@KeshaRose) January 22, 2014

This special request might be slightly creepy and bizarre, but it isn't the first time Ke$ha has crafted with human teeth. In 2012, the singer asked her followers to send her their teeth and she got a shockingly positive response.

"I asked for them to send me their teeth and I got, like, over 1000 human teeth," she told BANG Showbiz, at the time. "I made it into a bra top, and a headdress, and earrings and necklaces. I've worn it out."

So, who is ready to see what she comes up with this time?

UPDATE: From the sounds of it, Ke$ha is going to have to come up with a new artistic medium. The treatment center where Ke$ha is staying tells TMZ that they "can't accept human remains." This means Ke$ha's tooth project is being shut down — at least until she is released from the center.
