According to The Sun, Jamie has threatened to sack one of the security guards who 'let' his daughter be photographed bra-less in recent weeks.
A source told the newspaper: "Jamie's control over Britney's life is incredible. He hates the pictures of her with her nipples all over the place so he has banned her from leaving the house without a bra.
"He wants her to put across the right impression. One security guard was told he is close to getting fired because he lets her go out without her bra."
It is also claimed that Jamie forced Britney to break up with her boyfriend Jason Trawick.
"It was also Jamie who made her split with Jason," the source alleged. "He likes Jason but their relationship was too intense and volatile.
"He feared it was sending her back to her old ways. He warned her, 'It's Jason or your children'... Jamie means it all for the best."
