She may look, and most of the time act, like she doesn’t answer to anybody.

But it seems there is still someone who can keep Rihanna in check – her mother.

The 25-year-old revealed that mum Monica was less than pleased when she saw snaps of the saucy singer sitting pant-less by the fireplace.

Eyebrows were raised when the racy pictures, which were taken by her best pal Melissa, emerged showing her naked apart from wearing a see-through bra and what looks like a fur stole on her head.

While many people were delighted by the sexy images which show her sipping wine, her mother was less than happy.

Speaking to Elle magazine, she revealed: ‘I’m not afraid of any person other than my mother, but I’m terrified of her.

‘She called me two days ago and reeled me in about two 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 embarrassed. I felt like I got my ass whipped in front of my class at school. She humbled the f*** out of me.’

But despite her telling off, it doesn’t look like Rihanna, who is appropriately called Bad Gal RiRi on Instagram, has toned down her raunchiness.
