Jerry Lee Lewis is suing his daughter, claiming she isolated and abused him by giving him a diet of drug cocktails, reports TMZ.

According to court documents the “Great Balls of Fire” singer says that his daughter, Phoebe, took advantage while she managed her father’s career from 2000 to 2012, and conspired to spend his fortune with her husband, Ezekiel Loftin.

The documents allege that Phoebe forced Lewis, 81, to embark on grueling tours despite his fragile health. When he wasn’t forced to play piano she had him cooped up in a home that was so moldy he was forced to wear an oxygen mask.

The documents also claim that she fed her father a “heavy cocktail of psychotropic drugs” to keep him under her domain.

Last week the rock and roll legend sued his son-in-law Loftin for allegedly blowing through $5 of his fortune on real estate, plastic surgery and cars. But now he’s added his daughter to the suit.

Lewis wants to get his money back and bar the couple from using his name or likeness.
