Melbourne, Apr 21 : Britney Spears has "convinced herself" that her dad is drugging her to turn her into a zombie and stay in his control, according to sources.

The Hollywoodgossip. com reports that Jamie Spears is facing allegations, as the star wants out of his legally binding conservatorship, The Daily Telegraph.

"Britney is sure her father is out to get her and that he's drugging her to turn her into a zombie who won't fight back," a source told British magazine Look.

The source added: "Ever since her breakdown last year when she was hospitalised, she's been on several prescription pills to battle panic attacks.

"Her doctors have also prescribed anti-anxiety drugs Valium and Ativan to deal with stress and to help her sleep.

"As part of the court-ordered conservatorship, (Jamie Spears) has to make sure Britney takes the correct dosage because she forgets to take them." (ANI)
