The staff at Cliffside rehab facility have reportedly banned Dina Lohan from contacting her daughter after an incident that occurred on Lindsay's birthday on July 2nd. According to TMZ, the facility got Dina on the line to speak with Lilo but Mama Lohan didn't seem to have it all together. Sources tell the website that Lindsay's mom sounded intoxicated and the staff decided the conversation should not happen. The actress was also reportedly advised not to speak to her mother for the remainder of her treatment. Dina was also reportedly going to participate in family therapy with Lindsay and Michael Lohan last month but backed out after Michael publicly called her a liar.
