Britney Spears' father has forced the closure of one of the pop superstar's top fansites - because it keeps breaching copyright rules by posting unauthorized photos, lyrics and videos online.

Jordan Miller, the owner of BreatheHeavy.com, has been told to shut down his site after Jamie Spears took legal action against him.

In a message to fans on the site's front page on Friday, Miller wrote, "I have been battling the conservatorship Britney is currently placed under for months now. When I did not conform to the requests and demands Britney's management and father, Jamie Spears, recently put upon BreatheHeavy to stay quiet, they in turn became angry and malicious, launching, what I feel is an unjust attack, against me and my website."

Jamie Spears' lawyers demanded Miller's Los Angeles-based site be shut down by 3pm local time - or face legal repercussions.

Miller also wrote that one of Spears' lawyers told him "you are an uber fan who's gone a little too far."

He signs off with, "This conservatorship Britney is placed under, which controls every aspect of her life, is now clenching the future of her biggest fansite."

Miller is asking fans to donate funds so he can fight the legal action. If the site remains, Spears' legal team says it will pursue damages against Miller.
