Lindsay Lohan has reportedly been "begging" her mother to go into rehab.
'The Canyons' actress recently completed her own 90-day court ordered stint at the Cliffside Malibu treatment centre and is said to be urging Dina to seek similar treatment.
A source told RadarOnline.com: "Lindsay has been worried sick about Dina lately.
"She knows Dina has been out drinking and she sees how much her own treatment helped her, so she has been begging her mother to go and get help."
According to reports, the 27-year-old star is trying to get her mother to realise she needs help - but Dina apparently "refuses to listen."
The insider added: "Lindsay has been trying to get Dina to see she has a problem too and she needs to get help, but Dina refuses to listen and insists she doesn't have a problem and doesn't need rehab."
Those close to her family suggest Lindsay's own reluctance to seek help will be matched by her mother.
The source said: "Getting Lindsay to go, even though it was ordered by the court, was almost impossible and it seems like Dina is going to fight even harder than Lindsay did to stay out of rehab."
