Michelle Keegan topless bath photo on Instagram, Corrie's beauty saucy riddle online

London: Corrie's beauty Michelle Keegan sparked a saucy riddle last night — as a picture of a topless girl in a bath was posted on her Instagram page.

At the same time Michelle, 25, tweeted a photo of herself having a soak, but showed only her toes.

According to the Sun.co.uk report, the boob pic was deleted SIX SECONDS later — but not before hundreds of fans reposted it on Twitter.

Michelle — Tina McIntyre in the ITV soap — denied that she was the unidentified topless girl.

She blamed a prank by her pal Hayley Moynihan. Her agent Laura Graham insisted: “Her friend got her passwords.”

Michelle later tweeted her pal: “I’m gonna kill u!”
