The restraining order -- filed earlier this month by an aspiring actor/model named Samuel Barth -- just got the thumbs up by a judge during a brief hearing in L.A. County Superior Court.
As we first reported, Barth accused Lutfi of trying to diagnose Barth
with mental problems (just like Lutfi allegedly did to Britney) ... then
allegedly stalked him and members of his family.
Lutfi must now stay 100 yards away from Barth for three years.
