Lindsay Lohan has allegedly been advised by doctors to fire her mother Dina as her manager. The actress is currently undergoing rehab at the Betty Ford Clinic in Los Angeles and medics have warned her if Dina continues to focus her energies on her daughter’s career rather than being a parent to her, Lindsay will find it harder to beat her drug problems. A source said: “Dina needs to no longer act as her manager, or work for her daughter in any capacity. Lindsay needs Dina to simply be her mother. Lindsay’s treatment team at Betty Ford has emphasised this to Lindsay, very, very strongly.” The pressures of providing for her mother and siblings have taken their toll on Lindsay, 24, and doctors believe that by working for her daughter Dina has damaged their relationship. The insider told RadarOnline.com: “Lindsay feels the financial burden of taking care of her entire family. It’s enormous pressure for any person in their twenties, let alone someone battling with addiction. Lindsay and Dina don’t have a normal mother-and-daughter dynamic because of the length of time that Dina has worked for Lindsay.” Dina has also banned Lindsay’s father Michael from visiting their daughter while she is in rehab.
