Lindsay Lohan may be out of rehab, but she's not a completely free woman yet.

Her civil attorney, Ed McPherson says she's expected to go right into a "fairly rigorous outpatient" treatment.

Lindsay, who was released last night after spending just 22 days out of the original 90 she was ordered at UCLA Medical Center, "is doing very well," McPherson tells Us.

Another hearing is set for this morning at 8:30 with Judge Eldon Fox, presumably to discuss the terms of Lindsay's ongoing treatment.

Lindsay is not expected to attend, but X17online will be there LIVE so stay tuned here for all the action coming to you within the hour!
