Kate Beckinsale's "Underworld 4" Attire

Getting to work on her latest project, Kate Beckinsale took to the set of “Underworld 4: New Dawn” in Vancouver, Canada on Tuesday (March 15).

The paparazzi caught up to the beautiful brunette - who offered a first look in full wardrobe consisting of a leather catsuit, knee-high boots and long grey coat.

In the film, which is set to hit theaters on January 20, 2012, Kate reprises her role as Selene - who is described as "a gorgeous vampire with a vendetta against werewolves."

Filming started last month and during her time-off, Beckinsale jets back to Los Angeles to spend time with her daughter Lily Mo, 12, along with husband and former "Underworld" director, Len Wiseman.
