Rhianna says her mother would kill her if she ever posed naked for a men's magazine.

The 'S&M' singer is famed for her raunchy image and risque stage costumes but insists she would never fully strip off because her mum would be so upset.

She told Mondanite magazine: "My mother would kill me if I posed nude! My mother raised me with certain standards."

Although she won't strip off, Rihanna recently revealed she feels more comfortable the more naked she gets.

The 'You Da One' hitmaker admits she wears skimpy outfits because they increase her self-confidence and make her feel better about herself.

She said: "My way probably won't work for most people, but the more I got naked the more comfortable I felt. I just have to face my fear."

"You always find something wrong, you always find something you're uncomfortable with. One thing turns into another and you get embarrassed and self-conscious about it - you feel like everybody can see what you see."
