Ummm, Lindsay, what are you doing?  Between cigarette puffs, Lindsay Lohan breaks is down at The Lot.

Lohan seems to be performing the part of a toy soldier in the “Nutcracker” as she kicks, stretches, and does some very odd dance-like moves in the parking lot.

After feeling something amiss, Lohan sees the cameraman and discontinues her hilarious high stepping & walks away to torment others with this impromptu choreography.

See the video at TMZ.
