Rihanna posted a picture on her Instagram page where she can be seen flashing her almost naked toned bum.
The 25-year-old singer showed off her bum clad in skimpy red undies under denim shorts, which had been cut into a thong, the Sun reported.
The pop star uploaded the image, which was taken on the shoot for track Pour It Up, and wrote: "and that's a WRAP !!!!! pouritupvideoshoot."
She quickly deleted her post.
