Photographs featuring Rihanna, nude from waist down, were posted online by her friend, leaving the singer's mother very furious. Rihanna wears just a brassiere in the photographs, captured by her pal Melissa Forde, who subsequently posted them on Instagram, reports thesun.co.uk.

Despite frequently stripping off for the camera and smoking suspicious cigarettes, these particular pics of Rihanna left her mother Monica angry. She vented her anger at Rihanna over the phone.

"She called me two days ago and reeled me in about two naked pictures Melissa put up on Instagram - a sneak peek from a photo book she's making about me. She went crazy on me. I was, like, embarrassed. I felt like I got my a** whipped in front of my class at school," Rihanna told Elle magazine.
