It's pretty hard to believe she's a mother of two!
But Jessica Alba looks absolutely incredible in the new trailer for "Sin City: A Dame to Kill For."
The sequel to the 2005 movie has the actress, 32, reprising her role as Nancy Callahan, the stripper Bruce Willis' character falls for.
Just 1 1/2 minutes in it, you see Alba wield a pistol, smash her head into a mirror and show off her sexy dance moves.
The movie hits theaters Aug. 22 and also stars Josh Brolin, Joseph Gordon-Levitt, Bruce Willis, Mickey Rourke and Ray Liotta.
