Michelle Keegan has denied that an Instagram picture of a pair of naked breasts which she posted online and then quickly deleted belong to her.
The Coronation Street star, 25, put a picture of a woman's bare boobs in the bath on the social networking site last night, before taking it down again within seconds.
But several users had spotted the picture and screengrabs of it were quickly circulating online - with her name trending on Twitter.
So Michelle then took to Twitter herself to try to explain the mystery.
She appeared to suggest it was a prank by a friend, writing: "Phahahahahahahahaha @hmonners I'm gonna absolutely KILL u!!!! I'm CHANGING MY PASSWORD!! #touché u gave as good a u got! ;)"
And she then added: "Twitters going crazy! ... Sorry to disappoint guys, but they're not mine! Hahahahahaha!!!!! #Brilliant x"
When a follower said he was "gutted" that the lady lumps were not hers, she was still seeing the funny side, writing: "hahahahahaha!!!! Funny though!! I wouldnt mind! ;) xx"
Michelle is dating Mark Wright, the former The Only Way Is Essex cast member.
