Rihanna lashes back at an irrelevant Instagram user after family criticism

Rihanna has lashed out at an Instagram user for posting a derogatory remark about her family.

The 'Stay' singer uploaded an image containing a picture of a goat and the user asking her followers to 'spot the difference'.

Instagram user ms_kasharna1 responded to a picture of Rihanna and one of her relatives with "I swear everyone in Rihanna's family looks like they're retarded... Must be the drugs and alcohol!"

Rihanna responded by uploading a new picture on her own Instagram account of a picture taken from ms_kasharna1's profile alongside a goat. The picture was also posted on her Twitter feed, which is nearing 29.5 million followers.

ms_kasharna1 has since deleted all of her photos from her Instagram account, though her Twitter profile also sees her previously attacking the Bajan star.

One tweet reads: "Rihanna looks so dirty!!! Like she hasn't showered in days!", with another saying: "@Chrisbrown would just punch @rihanna in the face again".
