Fann Wong nude photo that stirred Singapore.

Singaporean actress Fann Wong caused a stir online after posting a picture of her pregnant self wearing nothing but two blue pieces of cloth.

The image, alongside another of her in a glittery gold dress, is from a celebrity endorsement campaign she is fronting with weight loss company Marie France Bodyline.

Called “She’s a Fann of ours”, the campaign involves a microsite that has four subsections with interviews, pictures and behind-the-scenes video.

The content was unavailable on Friday night, however, apart from a photo gallery with a single image.

Fann wong posted her pregnant photo to Instagram.
