Um... What the Heck is Lindsay Doing?!?!

We happened upon La Lohan last night doing an impromptu parking lot dance while smoking a cigarette. Between puffs, a lonely Lindsay started to break it down at The Lot, performing a weird combination of choreographed high-kicks, karate and stretches.

After noticing a cameraman shooting her somewhat ridiculous antics, she quickly stopped her dance, finished her smoke and walked inside.

Looks like that cast on her left arm hasn't kept kept her from her workout routine.
