Kesha isn't the only one in her family checking into rehab. The singer's 57-year-old mother told People Magazine that she too is entering rehab - the same one as her daughter - for Post-Traumatic Stress Disorder. Pebe Sebert told the publication that Kesha's struggles with an eating disorder are taking a toll on the entire family.

"I'm checking myself into Timberline Knolls today for post-traumatic stress disorder, at Kesha's urging," she told the magazine. "This whole Dr. Luke thing has almost torn our family apart and taken over my life, and Kesha wants me to heal along with her."

On Jan. 3, the 26-year-old "Tik Tok" singer announced that she was "seeking treatment for my eating disorder... to learn to love myself again. Exactly as I am." Right after Kesha entered the facility, her mom took to Twitter to lash out at music producer Dr. Luke.

Sebert claims Luke told Kesha she needed to quickly drop 15 pounds. On the set of one of the singer's music videos, Sebert told Radar Online that Luke called Kesha "a f**king refrigerator."

She also placed blame on several other members of Kesha's entourage. Sebert claims Kesha's advisor also put pressure on her to lose weight and told her he didn't care how she did it.

"It wasn't just Luke. She had an advisor who told her he had a meeting with a record company and they said she better lose 15 pounds in the next 30 days," Sebert said. "He told her he didn't care if she shoved her hand down her throat or took illegal drugs, but she had to lose the weight."

The outspoken mom also said another contributing factor was Kesha's split from a secret boyfriend. Reportedly, the "Timber" singer was dating music video director Darren Craig and she didn't handle the breakup that well. She claims the split not only triggered her eating disorder but also trust issues.
