Britney Spears’ is suffering from some extreme paranoia again. According to the latest gossip, Brit is convinced that her father/conservator Jamie Spears is drugging her to keep her under his control. The entire notion is especially suspicious given that Britney’s former “manager” Sam Lutfi admitted to Brit’s mother Lynne Spears that he drugged her, and Britney has been in communication with Lutfi and his accomplice/her ex-boyfriend Adnan Ghalib. Makes you wonder if Lutfi is planting the seeds of paranoia.

Britney Spears has a new fear — she’s worried that her dad is drugging her.The singer, 27, is currently under the conservatorship of her father, Jamie Spears. And Britney has “convinced herself” the patriarch is upping her medication to keep her subdued — so he can stay in control of her life.

“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. “Ever since her breakdown last year when she was hospitalized, she’s been on prescription pills to battle her 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 has to make sure Britney takes the correct dosage because she forgets to take them otherwise. But lately she’s been nodding off randomly in the middle of conversations and is convinced it’s because Jamie’s giving her too much much.” The source adds that Britney’s friends, “tell her it’s because she’s working so hard and performing every night on her Circus tour.”

But Britney, says the source, “thinks there is a more sinister reason and insists her dad is drugging her to keep her under control. It’s a bad sign that Britney’s paranoia is rearing its head again. She’s sneakily sent text messages to her ex-boyfriend, Adnan Ghalib, and told him she needs help because her dad is poisoning her. She’s desperate to untangle the conservatorship and get her dad out of her life.”

Last time Britney was drugged her behavior was incredibly bizarre. It’s hard to tell how much was due to a mental breakdown and how much was due to pills in her drinks. Obviously it would also depend on what she was being drugged with, but she doesn’t seem to be exhibiting any behaviors that would lead most people to think something duplicitous was going on.

Britney’s friends are right: nodding off a lot is much more likely due to her rigorous concert schedule (and strenuous performance routine) than being surreptitiously medicated. And if she’s eating sugary crap, that could make her tired too. I’d think it would be more rational to focus on getting more sleep and eating better – tenets of basic health – than assume her father is drugging her.
