Britney Spears' seedy manager / friend, Sam Lutfi, says the singer's mental problems stem from her parents, Lynne and Jamie Spears.
"Oh boy, her family is crazy!" Lutfi told Us Weekly in an interview.
"It's funny, because that's what the doctors say when they meet the family," he added. "They always come back and say, â€˜You know, [her problems] are inherited, right?' It's just so sad. It's shared equally from both of her parents."
When asked if Britney Spears trusts "a thing her parents say," Lutfi replied, "Not a g----n thing."
On Friday, Spears' parents went to L.A. Superior Court to seeking legal control of their daughter's finances and medical treatments.
Their requests were granted as a co-conservatorship was set up in their names, while Sam Lutfi was hit with a restraining order.
Sam Lutfi is speaking out against Britney Spears' parents.Â
When the singer heard Lynne arrived Sunday night, Sam Lutfi said Britney asked him, â€˜Is my mom really here?' I said, â€˜Yeah, she's here.' And she's like, â€˜Oh great, you know they're up to something.'
"They show up to the house like hillbillies, texting me," Lutfi said.
"I find out that they're outside, and they go, â€˜You better let me in the gate, you ass.' So I go, to Britney, â€˜Your parents are here, let them come in and yell at you and scream at you. If anything else goes on, I'll throw you in my car and take you out of here.' She said, â€˜OK, fine, baby.'
"I let them in. Instead of going to see how Britney is, they come bouncing through the doors. They scream at me, â€˜Why the f--k are you talking to Barbara Walters?' I swear to God that's all they were saying.
"The dad pushed me in the chest and said, â€˜Get the fâ€"k out of here.'
"The dad gave up and then the mom tried to talk to her, but Lynne was like, â€˜I gotta get my beauty sleep, I gotta get my nails done, I gotta do my hair.' It was just so sick. We made the mom stay."
Sam Lutfi said the singer suffers from "mixed state bipolar" and has had it for "roughly five years." A person suffering from "mixed state bipolar" experiences symptoms of mania and depression at the same time.
He said he has told the singer, "â€˜Britney, do you see why people think you are crazy? Look at your mother and look at your father.'"
