With a trip to rehab (by way of Coachella) looming over her head, Lindsay Lohan flew from NYC to LA yesterday for a stop on the red carpet.

The legally challenged actress was on hand for the premiere of "Scary Movie V" at the ArcLight in Hollywood on Thursday ... where she actually looked pretty great.

With her side-swept in a Coachella-ready braid, Linds looked good in her little black dress and mesh Louboutin heels.

And she wasn't the only sometimes-trainwreck at the event.

Heather Locklear and Charlie Sheen, who have both had their fair share of rehab run-ins in the past, also hit the red carpet. Like Lindsay, Locklear also looked healthy as she posed alongside her gorgeous daughter with Richie Sambora, Ava.

Other stars at the event included Ashley Tisdale (who went sexy in a cutout black gown), Mike Tyson and Kate Walsh.

"Scary Movie V" opens today in theaters.
