Lindsay, who's been staying in a Utah cabin with her father since checking out of Cirque Lodge on Oct. 5, was supposed to head back to LA over the weekend, but backed out last-minute. "She said, 'Dad, I don't feel ready to go back to Hollywood,'" Michael says. She opted to stay in Utah for outpatient treatment, under the watch of her sober companion and the Cirque counselors. "That's how committed Lindsay is to her sobriety. She doesn't want to do anything to mess it up. She's doing so well," Michael says. "She's doing whatever she can to keep the right influences around her this time, for as long as she can."

Lindsay will return to LA before Oct. 15, when she is scheduled to resume her role on the film Dare to Love Me. A sober companion will stay with her on set and go home with her. "Cirque representatives are looking for a place for her to stay," Michael says. "It will be somewhere safe, where she can continue her treatment."

And after the shoot, Lindsay's returning to Utah for more follow-up care. "That's her plan right now," Michael says.
