The Mean Girls star is currently serving out a three-month court-ordered stay at California's Betty Ford Clinic and she will continue to receive treatment at the facility until January (11).
Her most recent trip to rehab has cost her a role in Inferno, an upcoming biopic of porn star Linda Lovelace, with the film's director Matthew Wilder insisting he had to drop Lohan from the project as her personal problems made it "impossible" to secure insurance.
But Ethan Terra - who co-owns a production company with Lohan's mother Dina - is adamant the star will not have any troubles getting back to work once she is released.
He tells Fox News, "It's not fair in any way, shape, or form for those reports to be out there. Lindsay is 100 per cent insurable, all she had to do was put up a fee as a bond then she would have been paid upon completion. I could insure her today. She was definitely not fired...
"Lindsay has absolutely no qualms about getting work. She literally has a mountain pile of scripts to choose from. When she is ready, we'd like to see her take on a positive role; she is doing so amazingly well with her recovery."
