Britney Spears

Britney Spears has obtained a three-year restraining order against her former manager, Sam Lutfi.

L.A. Superior Court Judge Aviva Bobb also prohibited Lutfi's attorney, Jon Eardley, from coming within 100 yards of Spears and her family for the next three years. The order bars the men from contacting the singer via phone, mail or e-mail as well, People reports.

Spears' father and co-conservator of her estate, Jamie Spears, filed for a restraining order in January. He claimed that Lutfi, Eardley and Spears' ex-boyfriend, paparazzo Adnan Ghalib, conspired to gain control over Spears' affairs and have repeatedly tried to contact her.

Spears obtained a three-year restraining order against Ghalib last month.

Lutfi will appeal the ruling, his attorney said.
