LOS ANGELES - Britney Spears has obtained a restraining order against former pal Osama (Sam) Lutfi and one-time boyfriend Adnan Ghalib, court records show.

Lawyers for Spears and her father, who is her legal conservator, received the order Friday. The documents state Lutfi, Ghalib and lawyer Jon Eardley have been trying to gain control of Spears' affairs.

"On the first anniversary of the establishment of the conservatorship, the co-conservators are informed and believe that these three figures are working in concert to disrupt the conservatorship, with an utter disregard for Ms. Spears' health and well being," the documents state.

Lutfi was a manager and friend of Spears, whose mother once accused him of grinding pills into her food to control her. Ghalib, a paparazzo, had dated the singer.

The documents, released late Friday, claim Lutfi tried to contact Spears in late December by sending text messages to her hairdresser. The documents state Lutfi later started sending text messages to Spears and one of her lawyers, Blair Berk, trying to arrange a meeting.

The order, first reported Friday by the celebrity website TMZ, alleges Lutfi has also sent "anonymous, harassing and threatening" messages to Spears' father.

This week, the documents state, a lawyer sent a proposal to remove Spears' court-appointed lawyer. He later told Spears' lawyers he had been contacted by Eardley and Lutfi, the filings said.

Eardley once claimed to be Spears' lawyer and tried to get her conservatorship case moved to federal court. A phone message left at Eardley's office was not returned Friday.

Spears and her father agreed not to renew a temporary restraining order that was issued against Lutfi last year when it expired in July.

At the time, Spears' court-appointed lawyer Samuel Ingham issued a statement renouncing their friendship.

"Britney has made clear to everyone that she does not want to be further harassed or contacted in any way by Osama (Sam) Lutfi, now or at anytime in the future," Ingham said in a statement.

Lutfi at the time declined comment, saying only he and Jamie Spears had reached an agreement.

Spears was placed under the conservatorship a year ago Sunday. The arrangement has been expensive -- her estate has paid out hundreds of thousands of dollars in legal fees -- but since her father took control of her life, the pop singer has not had the bouts of erratic behaviour, including two hospitalizations, that led to his intervention.

She released her newest album, "Circus" in December on her 27th birthday and is preparing for an upcoming concert tour.
