Did Dr. Luke Fat-Shame Ke$ha Straight to Rehab?

Music producer Dr Luke may have some ‘splainin’ to do over reports that his fat-shaming drove a pop prodigy to rehab for an eating disorder.

On Friday, Ke$ha checked into the Timberline Knolls Facility in suburban Chicago for treatment of an undisclosed eating disorder.

“I’m a crusader for being yourself and loving yourself, but I’ve found it hard to practice. I’ll be unavailable for the next 30 days, seeking treatment for my eating disorder…to learn to love myself again. Exactly as I am.”

Sources close to Ke$ha, 26, claim Luke — who has worked with the likes of Britney Spears and Katy Perry — launched a weight-bashing campaign during Ke$ha’s 2011 Get Sleazy Tour. The music man was reportedly livid that the star had packed on a few extra pounds during a tour hiatus and he didn’t mince words about it.

Those in-the-know tell TMZ that Luke spent the next two years constantly making jibs about Ke$ha’s weight, even urging her management team to do something about it. During a music video shoot in 2012, Dr. Luke told the star she “looked like a f**king refrigerator” — an incident which Ke$ha was profoundly affected by, according to those close to her.

Dr. Luke hasn’t commented on Ke$ha’s decision to seek treatment, or allegations that he bullied her to an eating disorder. Signs of strife between the pair, however, have been apparent for months. In October, a deep rift between the singer and the super producer prompted thousands fans to a launch a “Free Ke$ha” petition in hopes of obtaining a label release and/or more creative control for the pop tart.
