The 24-year-old actress, who plays Rey in the new Star Wars installments, posted the hilariously unnerving pic to Instagram on Thursday, which she captioned, "@riancjohnson and I face swapped and it was awesome and terrifying."
In keeping with the theme of on-set confidentiality, on Wednesday, Ridley posted a video of her intense workout routine but had to keep a "pillowcase" wrapped around her head to "protect my REY HAIRSTYLE from Instagram's gaze."
Recently, Ridley spoke with ET while promoting the home media release of The Force Awakens, and the English star opened up about what it was like on set of Episode VIII, with Johnson at the helm instead of J.J. Abrams, who directed Ridley in Episode VII.
"It's still very lovely and warm and friendly," Ridley shared. Check out the video below to hear more.
