Blake Lively and Ryan Reynolds are quickly becoming one of the funniest celebrity couples on Instagram. Over the weekend, the good-looking duo once again showed off their sense of humor with a tongue-in-cheek 'gram that verged on naughty.

In the photo, Lively perches on her husband's lap as he sits on a Deadpool-themed throne. While that isn't too risqué on its own, Reynolds's sly smile in contrast to Lively's severe expression as he cups her breast is pretty funny. "Two Deadpools, one cup. Your turn," she captioned the photo alongside the film's official (and very clever) hashtag.

Reynolds has been busily promoting his upcoming film Deadpool on his social media channels, and Lively has definitely been doing her part, too. The actress recently attended a surprise screening of the flick, and took to Instagram to rave about the film and her very sexy husband.
