Britney to Sam Lutfi: It Was Nice Knowing You...

Britney Spears' conservatorship was just granted a permanent restraining order on Brit's behalf against Sam Lutfi and a guy who once claimed to be Britney's attorney.

The restraining order lasts until April 28, 2012.

Britney and both her sons, Sean Preston and Jayden James, are protected under the order. Lutfi and Jon Eardley are not allowed to go within 100 yards of Brit's home, job or workplace.

Sam and Jon also have to stay away from K-Fed's place and any of Britney's family members' homes.

The conservators filed for the restraining order because they said Lutfi and Jon were trying to torpedo the conservatorship by contacting Britney behind their backs.
