Marnie Simpson has given everyone an early Christmas present this week in the form of a secret, and it's all to do with her bum.

You're welcome.

Chatting in her Star magazine column, Marns explains how you too can take sexy snaps just as incred as hers all with a tilt of the bum.

'I know I post a lot of sexy pictures on Instagram, but my photographer friend takes them for me and I'm totally comfortable with being naked in front of her,' she explained.

'I posted one last week of me in the shower and some people said how good my bum looks.

'But I'll let you into a secret - I was really pushing it out and my back was almost bent in half!'

Brb, just going to work on our back flexibility.
