John Legend's model fiancee Chrissy Teigen has stripped off for the R&B star's sexy new music video.

The singer has chosen his wife-to-be to star as his leading lady in the promo for All of Me and it appears the couple will be giving fans a sneak peek at their life in the bedroom after a semi-nude shot of the pair onset surfaced online.

The black and white picture, posted on photo-sharing website by snapper Nabil, shows Legend in bed with Teigen, who bares her breasts for the cameras while a bedsheet covers her mid-section to preserve some of her modesty.

Nabil uploaded the image on Thursday morning (12Sep13), and proud Teigen alerted her fans to the snap by retweeting a link to the shot.

The revealing photo prompted a few criticisms from her followers, but Teigen fended off the comments by insisting, "Literally everyone has a nipple. Get over it."
