Blake Lively has undergone a serious make-under for her new role as a spy and assassin in the upcoming film The Rhythm Section. Paparazzi photos from the set in Dublin over the weekend show the actress in a shaggy, dirty blonde bob and baggy sweats, looking basically unrecognisable.

Her husband Ryan Reynolds reacted to the pictures with an Instagram post. "#nofilter," he captioned the snap.

Lively appeared to be a good sport about the joke, and commented, "Only the best for SMA 2010." She appeared to be joshing back at husband, who was crowned Sexiest Man Alive in 2010 by People magazine.

Lively, 30, and Reynolds, 41, tied the knot in 2012 and have been cracking jokes at and with each other ever since. The Deadpool star's latest Instagram is just the latest at his and the actress' back-and-forth.

Before his #nofilter post, Lively trolled Reynolds on his birthday with a picture of Ryan Gosling. "Happy Birthday, baby," she captioned the photo.

And earlier in the year, she congratulated him on his TIME Most Influential People nod—with a photo of John Legend.

Not to be outdone, however, Reynolds pulled similar pranks on his wife on his own Instagram. On her birthday, he posted a photo of them together, but cropped her out. "Happy Birthday to my amazing wife," the actor captioned a post of basically just himself.

And he celebrated the premiere of her film, All I See Is You, by joking that he and Lively had never met before. "Also, I married my wife online, so it was nice to finally meet her in person," he wrote in the caption.
