When Lindsay Lohan
leaves Utah to finish filming Dare To Love Me
in Los Angeles, she will have round-the-clock help staying sober, her dad said.
To insure the 21-year-old actress continues her recovery from alcohol and drug abuse, a sober companion, trained to be with people overcoming addictions, will be with her, Michael Lohan told PEOPLE.
On Oct. 5, Lohan left rehab
at Utah's Cirque Lodge Treatment Center, which helped the actress find the companion.
"Lindsay's companion is really, really tough, and she's really nice, she's an amazing lady, a great influence on Lindsay's life," the elder Lohan said before attending a family court hearing in Westbury, N.Y., concerning his youngest children Ali, 13, and Dakota, 11.
He also talked about another part of her new life – beau Riley Giles
, whom she met in rehab. "He's a great, great kid," Lohan said. "If you met him, you'd like him."
Lohan does not know where his daughter will be staying in L.A., but after filming – slated to begin Oct. 15 – he expects her to come back to Utah to live, receive continued counseling and attend Alcoholics Anonymous meetings. "It looks like she may have already found a house," he said, noting that she currently stays in a rental near the lodge.
And he's definitely not concerned about reports of her going out at night to establishments that serve liquor. "She goes out, she goes out," he said. "She does the right thing."
