Jessica Alba is Blond and Packing Heat for ‘Sin City 2′

Jessica Alba is slinking into a pair of sexy chaps again in 'Sin City: A Dame to Kill For', but this time she's ready for action. After the first 'Sin City' saw Alba's character, Nancy Callahan, play damsel in distress to Nick Stahl's lemon-colored pervert, it would appear as though the stripper - we're sorry, exotic dancer - has finally decided it's time to pack some heat. After all, Bruce Willis can't come to the rescue anymore.

Via her official Twitter page, Ms. Alba recently gifted her followers with a few photos of her transformation into Nancy; first displaying her freshly-dyed blond hair, then tickling the fancies of 'Guns & Ammo' enthusiasts everywhere by showing off the above images. (Said images could really change some minds on the Second Amendment debate, by the way.) Alba has been generous in this way before: A couple months ago, Alba shared a look at her in 'Machete Kills' mode. Does Robert Rodriguez know his actress is lifting the veil on his top-secret sequels?

It makes perfect sense that Nancy load up in this 'Sin City 2', the only question is, what the hell took so long? You live in Sin City, girl! Even the prostitutes are blood-thirsty killers!

'Sin City: A Dame to Kill For' also stars Mickey Rourke (and a plethora of as-yet-unnamed stars) and is scheduled for release in October 2013.
