Ke$ha will reportedly receive help for her heavy drinking while in rehab.
The 'Timber' singer checked into a treatment facility earlier this month after admitting she is suffering from an eating disorder, and she will also address her alcohol consumption in a bid to be "completely healthy".
A source told RadarOnline.com: "In recent months, those closest to her had become increasingly worried about her drinking. It's been the stuff of legend in the past and she's never hidden the fact that she loves to drink.
"Now, though, part of her bid to get healthy is to get completely healthy -- and that will involve looking at her abuse of alcohol. Some of her advisers had raised this in the past."
However, insiders insist that the 26-year-old star's main reason for seeking treatment at Timberline Knolls near Chicago is just her eating disorder.
The source added: "There's no doubt that Ke$ha has her demons and the chief one is an eating disorder. "It's the primary reason she checked into Timberline Knolls."
The 'Tik Tok' hitmaker released a statement last week revealing she was entering rehab. She said: "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."
