London, April 29 (Inditop) Pop star Britney Spears’ former manager Sam Lufti has been ordered to stay away from the pop superstar for three years.

Los Angeles Superior Court Judge Aviva Bobb issued a harsh restraining order against Lutfi and his legal associate Jon Eardley April 28, reported contactmusic.com.

Both men must stay at least 100 yards away from Spears, her two sons, and her family members’ homes. Under the terms of the new order, they cannot contact the singer via phone, mail or email.

Spears’ father Jamie filed the restraining order request in January after learning Lutfi had attempted to contact his daughter over Christmas, going so far as to smuggle a cell phone to the singer in a hotel.

Lutfi has filed a lawsuit against the Spears family for defamation and battery.
