In response to the image, Pugh's boyfriend, Scrubs actor, Zach Braff, commented a princess emoji on the post.
But the social media move sparked widespread backlash with a number of followers calling out the 21-year age gap between the pair.
Pugh’s boyfriend, Scrubs actor Zach Braff, who she was first linked to in April 2019, commented a princess emoji on the post, prompting one of Pugh’s fans to point out his age.
"You're 44-years-old," one social media user wrote.
Unfazed by the criticism, Pugh simply clapped back: "And yet he got it 👌🏽".
The couple are rumoured to have met whilst working on short film In The Time It Takes To Get There which saw Pugh grace the screen while Braff sat in the director's seat.
Since the film debuted in April 2019, the pair have been spotted holding hands on multiple occasions whilst out and about in the Big Apple.
Most recently, Braff attended the world premiere of Little Women on December 2 in support of Pugh although they chose to pose for solo photographs.
