Dina Lohan -- Lindsay Will Be Out 'Soon'

Lindsay Lohan was ordered to 90 days of rehab -- but, according to her mother, she won't be doing the full time.

Dina Lohan was just on "Today," where she said Lindsay will have a shorter stay at UCLA and will be out "soon" -- adding that Linds made friends with a lot of "alleged murderers" during her incarceration before rehab.

As TMZ previously reported, the inpatient program at UCLA typically lasts only 45 days, but doctors often repeat the program or stylize another program for the patient that could easily last 90 days.

Lindsay's lawyer, Shawn Chapman Holley, told TMZ doctors have not yet determined how long of a stay is appropriate.

Although the judge could let Lindsay out early, sources tell us it's very unlikely.
