Lindsay Lohan was a no-show at the premiere of her new movie "Machete" last night in L.A. -- and from the looks of it, she missed one cool fiesta!

The rest of the film's cast packed The Orpheum Theatre, where Jessica Alba stood out in a sexy, sparkly, gold and black dress -- which she paired with some hot Louboutins.

Cheech Marin, Don Johnson, Michelle Rodriguez all showed up in old school lowriders, while star Danny Trejo pulled up on a motorcycle.
