Dina Lohan 'drunk dialed LiLo during therapy session'

Lindsay Lohan's mum, Dina Lohan, has allegedly been barred from participating in her daughter's rehab treatment following a suspected drunken phone call a few weeks ago.

Sources told TMZ.com that shortly before the 'Mean Girls' star's birthday on July 2, Cliffside rehab facility arranged for Dina to talk to Lindsay on the phone.

The insider claimed that after the clinic dialed Dina, they realised that she was completely drunk and nixed the call.

Moreover, the source told the gossip site that the rehab team felt it would be best for the actress' treatment if she stopped talking to Dina altogether for the rest of her stay.
