Rehab didn't exactly turn out as planned for Robbie Williams.
Although the British singer hasn't relapsed and is reportedly still working on his prescription drug addiction in the real world, he is about to be sued by the clinic that made him healthy.
Williams left the clinic early, and after entering the 'real world' of the L.A. club scene again, said the Cottonwood de Tucson center was "worse than a concentration camp."
The treatment center is not impressed with Williams' description. A source from the clinic told Britain's Daily Star Sunday newspaper, "We're one of the most respected rehabs in the world and what this man has said is outrageous. Board members have taken legal advice and have been told they have a defamation case against him. Everyone on staff is backing their action 100 percent."
Williams only stayed in the center for a few weeks and since he left, has been spotted leaving nightclubs.
