A little seemingly harmless filtering paired with Moss' hand placed on Marni's thigh has made it look like the bronzed brunette only has one leg.

"Smoothed and edited the leg became one," a user commented.
"How's the editing on the legs," said another.
But the duo seemed unphased by the comments, probably because they're busy enjoying the Bali sun!
After meeting on reality dating show Love Island Australia (which was filmed in Spain), the pair officially confirmed their relationship in August last year.
