Pop diva Britney Spears seems to have come to the end of her tether, for while she was stripped to check for concealed drugs at rehab, a "Death List" of people she wishes would die was found on her.
The list includes American paparazzi and her estranged husband Kevin Federline , with whom she is locked in a bitter battle for the custody of her sons, reports the Newsoftheworld.
She also offered Kevin £100,000 to drop a custody hearing over their two sons and believes she is being bugged as she sleeps and checks every morning for listening devices.
The increasingly paranoid star was pictured shuffling around the grounds there, haggard and lost, wearing a scruffy blue hoodie and sucking on cigarettes.
The former pop princess wed Federline in September 2004 and filed for divorce last November after reports he was gambling away her fortune and cavorting with hookers in Las Vegas.
"This is rock bottom—this is as low as Britney can go. We're just terrified of what might happen next," a pal of the singer said.
"They had to strip search her afterwards to make sure she didn't have drugs on her body. Then the list was quietly disposed of. Britney just turns this stuff over and over in her mind. She has dark fantasies about terrible things happening to her enemies," he added.
