The Coronation Street star's account sent out a photo of a woman's naked torso tonight (April 4), but the snap was deleted within seconds.
Keegan's name began trending on Twitter as many users shared the screengrabbed image and speculated on whether it really was Keegan in the picture.
However, the 25-year-old quickly took to the microblogging site to reveal that she had been the victim of a friend's prank.
Twitters going crazy! ... Sorry to disappoint guys, but they're not mine! Hahahahahaha!!!!! #Brilliant x— michelle keegan (@michkeegan) April 4, 2013
She went on to respond to a follower who said that he was "gutted" the photo wasn't of Keegan.
She quipped: "hahahahahaha!!!! Funny though!! I wouldnt mind! ;) xx"
Keegan is currently in a relationship with Take Me Out: The Gossip co-host Mark Wright.
Wright was also recently forced to use Twitter to reassure fans that the couple weren't going through any trouble, after "a bit of banta" got "twisted 2 look bad".
