Ke$ha says she is 'feeling healthy' after leaving rehab
The singer has been in a Chicago facility being treated for an eating disorder
The singer took to Twitter to announce the news, telling her fans that she is now working on new material.
"Happy to be back! Feeling healthy & working on tons of new music," she wrote. "I can't thank my fans enough for all the love & support u have given me".
During her time in rehab, it emerged that the pop singer's fans had been banned from sending her their teeth as a show of support. The singer uses the teeth to create art and accessories and was inundated with packages from fans.
A spokesperson for the treatment facility explained that health and safety reasons were behind the decision: "We can't accept human remains. There is always a risk it could be bio-hazardous material so we are not able to bring in anything that's real," they said.
Ke$ha's mother recently attacked producer Dr Luke and members of her daughter's advisory team after the singer entered rehab.
Around the same time, Ke$ha hit Number One in the Official UK Singles Chart with her track 'Timber', a collaboration with rapper Pitbull.
