Ke$ha's mother, Pebe Sebert, has joined Kesha in rehab, to seek treatment for post-traumatic stress.
"I'm checking myself into Timberline Knolls today for post-traumatic stress disorder, at Ke$ha's urging," Sebert told People Jan. 11. "This whole Dr. Luke thing has almost torn our family apart and taken over my life, and Ke$ha wants me to heal along with her."
Kesha entered a 30-day rehab program on Jan. 3 to get treated for the eating disorders bulimia and anorexia. Ke$ha reportedly told friends that her eating disorder was caused by her music producer, Lukasz "Dr. Luke" Gottwald, who had repeatedly called her a fat "f**king refrigerator."
Sebert confirmed that Dr. Luke's fat-shaming comments drove Ke$ha to diet drastically, lose a dramatic amount of weight and fueled her anorexia and bulimia. Dr. Luke vehemently denied that Kesha's eating disorders were caused by his weight bullying.
Meanwhile, Sebert slammed rumors that Kesha is being treated for drug and alcohol addiction. Sebert, a recovering drug addict and alcoholic, said her daughter used to accompany her to Alcoholics Anonymous meetings as a child, and those experiences deterred her from becoming addicted to alcohol or drugs herself.
“Kesha's been going with me to AA meetings since she was just over a year old," said Sebert. "She’d never touch cocaine because that was one of my vices. She’s always said she never wanted to do the same thing I did.”
Sebert added that Kesha eventually wants to use her bulimia as a platform to educate her fans about the dangers of eating disorders. “She wants to be a voice for this," said Sebert.
