Lindsay Lohan's Ex-Lawyer Shawn Holley -- Freedom Feels GOOD!!!

Lindsay Lohan's former mouthpiece Shawn Holley showed up this AM to the scene of the crime, sort of ... the courthouse where LiLo copped a plea Monday ... and Shawn coyly looked and sounded like a woman who has had a 118-pound weight lifted from her chest.

Shawn did watch our livestream yesterday, and guess what she found most entertaining?
