Demi Moore has found herself on the receiving end of one of Ashton Kutcher's Twitter pranks again.

The former Punk'd mastermind posted a digitally-enhanced photo of his wife's dramatic new haircut on the micro-blogging site – a Mohican.

He wrote: "Wifey just got a new hair cut, what do you guys think? I love it."

Playing along, Demi replied: "I have the buzzer ready baby."

Apparently keen to make the edgy new cut a reality, Ashton Tweeted back: "I'm just playing baby but I think you'd look great with that cut."

Demi proposed going a step further: "Thank you love. How' bout I shave your initials into my head."

After Ashton saucily suggested she could shave his initials somewhere else on her body, Demi played innocent, replying: "Like my armpit?"

We think she should go for it - if Rihanna can pull off a Mohawk-inspired 'do, why not Demi?

Earlier this year, Ashton treated his Twitter followers to a picture of his wife's panty-clad bottom.
