Britney Spears' father has branded the #FreeBritney movement a "joke".
The 38-year-old singer has been under a conservatorship since her highly-publicised meltdown in 2008, and fans have in recent years created an online movement campaigning for her to be put back in charge of her own affairs.
However, her father Jamie - who was conservator of the 'Toxic' singer's affairs until stepping down last year due to health reasons - has slammed the "conspiracy theorists" and insisted they "don't know anything".
Branding the movement "a joke", he added to the New York Post newspaper: "All these conspiracy theorists don't know anything. The world don't have a clue.
"It's up to the court of California to decide what's best for my daughter. It's no one else's business."
The 68-year-old patriarch also blasted rumours that he or others have been taking money from Britney's estate.
He fumed: "I have to report every nickel and dime spent to the court every year. How the hell would I steal something?"
And Jamie suggested he'd even had death threats from #FreeBritney campaigners.
He said: "People are being stalked and targeted with death threats. It's horrible. We don't want those kinds of fans.
"I love my daughter. I love all my kids. But this is our business. It's private."
