Rihanna was severely reprimanded by her mother after a set of naked pictures of the star appeared online last month.
The singer was shown undressed in two photographs taken by her friend Melissa Forde as part of a new picture book project, and Rihanna's mom Monica was furious when the images hit the web.
Rihanna reveals she is "terrified" of her mother and felt "humbled" by her harsh words.
She tells Britain's Elle magazine, "I'm not afraid of any person in this world but my mother, I'm terrified of her! She called me two days ago and reeled me in about two naked pictures Melissa (Forde) 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! She humbled the f- out of me."
