Photos of a smiling young woman with her motorbike proved popular with social media users in Japan and began to notch up hundreds of likes, writes BBC.
But some eagle-eyed followers noticed things did not add up; her arm seemed very hairy in one photo, and a mirror reflection showed a different face.
A TV show revealed the star of Twitter user @azusagakuyuki was actually a 50-year-old man named Zonggu.
He admitted to using photo editing apps to create his alter ego.
