Ashton Kutcher Posts Photo Of Demi Moore's Butt On Twitter

Ashton Kutcher has posted a picture of wife Demi Moore in her underwear on his Twitter page.

The professional prankster is a big fan of the micro blogging site and constantly updates his followers with his innermost musings and personal pictures.

But his famous wife has largely been a no-go area – until now.

Ashton's latest picture share features a derriere that is supposed to belong to Demi as she bends over away from the camera in her knickers, apparently unaware that her picture is being taken.

The cheeky scamp tweets that he is "watching my wife steam my suit while wearing a bikini. I love God!."

He adds, "shhh don't tell wifey."

Ashton has previously posted a video parody of Michael Jackson's infamous baby-dangling incident, and controversial footage of him filming himself while riding his motorbike around L.A. one-handed.

We wonder what Demi makes of his latest update...

Guess the owners of these delectable derrieres
