Rihanna, who was born in Barbados, politely asked the paparazzi to stop taking pictures. She has avoided the paparazzi in the US since May because Americans are shamefully fatphobic and rude.

After the photos surfaced online, Twitter users fat-shamed Rihanna and mocked her post-baby weight gain.

The rude tweets sparked a war of words between Rihanna's Navy and the trolls who called her fat.
