The 26-year-old actress is due to check into a residential facility for 90 days as part of a plea deal she agreed last month in relation to a car accident, reported New York Daily news.
"I think, to be honest, I'm the happiest when I'm working and the healthiest, and I think this an opportunity for me to, you know, focus on what I love in life. And I don't think it's a bad thing. I think it's a blessing ... And not a curse," Lohan said on a Late Night TV show.
Lohan has checked into rehabilitation facility five times before.
