Former manager Sam Lutfi also banned from contacting singer

Britney Spears has obtained a restraining order against ex-boyfriend Adnan Ghalib and her former manager Sam Lutfi.

The singer’s lawyers filed papers at the LA Superior Court on Friday claiming the pair have been trying to undermine the authority of her dad Jamie, who has been her conservator for a year.

The document alleges that they’ve been ‘working in concert to disrupt the conservatorship, with an utter disregard for Ms Spears‘ health and well being.’

The temporary order means Adnan and Sam are banned from contacting Britney, 27, her parents and sons, Sean Preston, 3, and Jayden James, 2.

A hearing is set for 23 February.

Adnan and Sam were unavailable for comment.
