Lindsay Lohan -- Out of Rehab, Headed to Sober Coach

90 days in rehab didn't make Lindsay Lohan modest -- 'cause she wasted no time showing off her legs moments after leaving Cliffside Tuesday afternoon.

Lindsay was sporting a huge smile, a blue print mini-dress, suede-fringe jacket and some major baggage -- a big blue one -- as she got into the SUV that picked her up from the Malibu facility.

Sources close to Lindsay tell us she'll be staying with a sober coach somewhere in Los Angeles for the next few days.

As we previously reported, Lindsay's telling people in her life she feels like she needs a transition period before re-entering the real world on her own.

Lindsay checked into the Betty Ford Center back on May 2 to begin her court-ordered rehab stay -- and transferred to Cliffside in mid-June.

Gotta say, so far ... she's looking good.
