TMZ:

Lindsay Lohan is a free woman ... for around 15 hours - LiLo got a one-day pass at Betty Ford to celebrate Thanksgiving ... in L.A. ... with her dad.

Sources close to the actress tell TMZ, she's leaving her sober living facility in Palm Springs this morning to make the 2-hour drive ... but she has to be back by late tonight.

We're told a bunch of Lindsay's friends are coming to dinner ... along with Michael Lohan
