Britney's dad has been trying for months to get her committed into a mental hospital

Britney's dad has been trying to get her committed into a mental hospital for a bipolar disorder. But he's not the only family member.

Jamie Spears has felt since last summer that Brit was suffering from a mental disease and not substance abuse. Jamie was looking for a way to push his daughter into a facility but she refused. Indeed, we're told she refused and continues to refuse to undergo tests that would officially diagnose the bipolar disorder.

Jamie and Lynne Spears believe Sam Lutfi, the guy who was inseparable from Brit until last week, was a prime reason she was refusing treatment. They dislike Lutfi so much that they threw him out of Britney's Cedars Hospital room last week.
