Lindsay Lohan will no longer play famed porn star Linda Lovelace in the biopic Inferno.

"We are withdrawing our offer from Lindsay Lohan," director Matthew Wilder tells E!.

While it may seem a harsh strike against Lohan 24, who is currently in rehab at the Betty Ford Center in California, the director says it's not personal, it's business.

"We have stuck by Lindsay very patiently for a long time with a lot of love and support," Wilder says. "Ultimately, the impossibility of insuring her -- and some other issues -- have made it impossible for us to go forward."

No word yet on who will take Lohan's place, but an announcement is imminent. "We are currently in negotiations [with another actress] and working out the legalities of bringing her onboard."
