Whose bare behind?We haven't seen a peachy posterior like this for a long time.

(It's tricky to look in the mirror, you know.)

But you' ll never guess whose rump this is.

The bottom in question is making an appearance in a feature-length horror flick.

Unfortunately the flick, titled Boogeyman 3, is not so perky as the behind and is going straight to DVD.

So just who's the lady behind the butt, starring in this cheeky role?

Well hold your breath folks... it's our very own Corrie babe, Nikki Sanderson.

Yes, the actress best known for playing Candice Stone is forging a career in film.

Nikki plays the part of Audrey, a college student who witnesses the alleged suicide of heNikki Sanderson r roommate in the flick - due for release this year.

It sets into motion a series of horrific events that cause her to fear the supernatural entity known as the Boogeyman. 

Nikki strips off to nothing in one particularly titillating bath-time scene.

While the flick isn't going to get any Oscar nominations, you bet we'll be racing straight to the local rental.
