Ashton Kutcher and Demi Moore. (WENN.com file photo)

Ashton Kutcher has risked incurring wife Demi Moore's wrath - by posting a picture of the actress' bottom on the Internet.

The couple was in the Turks and Caicos Islands to attend the wedding of Moore's ex-husband Bruce Willis to model Emma Heming on Saturday.

And Kutcher celebrated the event by mischievously taking a picture of the Ghost star bending over while wearing a bikini - and then posting the sneaky snap on social networking site Twitter.com.

He wrote: "Watching my wife steam my suit while wearing a bikini. I love God! I'm not wearing the bikini, she is -that's what makes it so glorious."

Captioning the photo, he added: "Shhh don't tell wifey."
