She's also rocking a pair of purple baggy sweats and some serious under-eye bags.
Blake was dressed in that attire because she was in the middle of filming a new movie, The Rhythm Section, which is being shot in Dublin, Ireland.
Blake and Ryan married in September 2012 after meeting on the set of the Green Lantern in 2010 - while Ryan was still married to Scarlett Johansson. For the film, Lively portrays Stephanie Patrick, a woman who is seeking revenge against those who orchestrated a plane crash that killed her family. In April 2016, when he ascended on the stage of the MTV Movie Awards to retrieve a price, Ryan Reynolds made use of his excellent second degree, to thank his wife, saying: "I want to thank my wife: everything I do, I do it to make her laugh, especially c*l".
This photo was taken on the set of Lively's upcoming thriller, The Rhythm Section, which is based on the best-selling book series by Mark Burnell.
Her costume is very dishevelled and believe it or not, in this film, Blake is actually supposed to be playing an assassin!
While the transformed style has stirred quite a buzz on social media, even impressing fans, Lively was hardly thrilled with the idea of women looking "likeable" on-screen at all times.
In August, Reynolds shared a birthday message for his wife but cut her mostly out from the photo he shared.
We're sure to be treated to some more hilarious posts as the filming continues.
Blake then hit back by posting a birthday message to her husband, with a photo of Ryan Gosling instead Of a photo of him.
