There is a lot of behind-the-scenes anger surrounding the Britney Spears' intervention, and the anger is directed at one Sam Lutfi, pictured here with Brit and mama Lynne today at Beverly Hills Mercedes.
As TMZ first reported, the family is staging an intervention so Britney can get help for her bipolar disorder. Family sources say they are furious at Lutfi, claiming he pushed Brit into going to B.H. Mercedes today to buy a new car -- in the middle of the effort to save her.
One source says the family believes Lutfi has been a "counterproductive, disquieting force" who has done nothing but harm.
