Blake Lively, one of the most glamorous actresses out there, is really getting into character in Dublin, where she’s presently filming The Rhythm Section, a thriller which sees her playing an assassin.

Blake was pictured on Monday on set looking anything like her usual self.  Baggy sweatpants? Check.  Oversized t-shirt and dirty looking parka? Check.

Long blond tresses impeccably styled and makeup perfectly applied? Nope.

Blake looked like a bum, and worse, her character smokes so she was photographed puffing away on a cigarette.

The Rhythm Section, described as a “female-driven international espionage thriller,” is an adaptation of British writer Mark Burnell's novel.  No word on how long Blake and Co. will be in Dublin, but at least she’s got company there.  Her hubby Ryan Reynolds and their two daughters are reportedly with her, basing themselves in the exclusive suburb of Dalkey.
