A source tells RADAR Online, "Dina and Lindsay both need to go to rehab to deal with their addictions, and they need to get treatment separately. Dina has been acting like Lindsay's friend and not her mother for a very, very long time. Who goes nightclubbing with their mother until in the morning? Lindsay was tape recorded by her father, Michael, in which she said Dina had been doing cocaine that night. Lindsay, as someone who has been in rehab in the past, shouldn't be around anyone doing drugs, let alone be going to nightclubs and partying! Friends of Dina and Lindsay genuinely fear for their safety and well-being. Dina and Lindsay are in absolute denial about their addictions, and are refusing to get the help they so desperately need.''
