Lindsay Lohan's sentencing on Tuesday to 90 days in jail and 90 days of inpatient rehab is having repercussions for both her family and her career, producers and her parents have said in the aftermath.

Los Angeles County Sheriff's Department spokesman Steve Whitmore told "Access Hollywood" that nonviolent females in the system generally serve 25 percent of their sentence, meaning Lohan could be out in as few as 22 or 23 days. After rehab, that means she would not be free to shoot or promote her movies and other projects until November.

That will be too late for director Robert Rodriguez's September release "Machete," in which Lohan, 24, has a supporting role. The film's distributor, 20th Century Fox, had no comment for The Associated Press Wednesday. But Matthew Wilder, director of "Inferno: A Linda Lovelace Story," told AP he is "100 percent behind Lindsay," who stars as the ultimately tragic adult-film performer. The film reportedly was set to begin shooting in August.

Kerry Wallum, a producer who was in negotiations for Lohan to co-star with Johnny Knoxville in Willie Nelson's comedy "The Dry Gulch Kid," told AP, "We're behind her. We'll wait until all of this blows over."

In an interview taped Wednesday for E! News, Lohan's father, Michael Lohan, said, "When I look in her eyes, it's scary; she's lost, it's not her - she's surrounded herself with dark people in a dark place and [she] needs to get out."

Mom Dina Lohan in a statement to AOL's PopEater.com, said, "This is so not fair to do this to my child."

Sheriff's department spokesman Whitmore told RadarOnline.com that when Lohan surrenders July 20, she will serve her time at the all-female Century Regional Detention Facility in Lynwood, Calif.
