LINDSAY LOHAN Jail Scares the Crap Out of Me ... So I Chose Rehab

We broke the story ... prosecutors have offered Lindsay the 90-day lockdown rehab deal for weeks, but she consistently rejected it. Her change of heart came at the last minute -- 30,000 feet in the air as she belatedly flew to L.A. for her trial.

LINDSAY LOHAN Jail Scares the Crap Out of Me ... So I Chose Rehab

Lindsay is telling friends she actually likes the rehab option, because it will allow her to focus on herself without any distractions.

Lindsay has been down this route before, but the rehab experience has never stuck.
