Ke$ha wants fans' teeth for rehab art project

Ke$Ha has asked fans to send her their teeth for an art project she is working on in rehab.

The singer checked into the Timberline Knolls clinic in Illinois earlier this month (Jan14) to receive professional help for an eating disorder.

She reached out to fans on Twitter.com earlier this week (beg20Jan14) to thank them for their support, and now the TiK ToK hitmaker has issued a bizarre request in the name of art.

A pal tweeted the message from the singer's social networking account on Tuesday (21Jan14), writing, "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."

Ke$ha previously made a necklace out of fans' teeth in 2011.
