The `Only Girl (In The World)` singer has turned down an offer to bare all for adult publication Playboy, though she admits she would be open to stripping off if it was on her terms.
She told Angie Martinez of New York`s Hot 97 radio station: "If I`m gonna take my clothes off, it has to be in a classy way and my will, not a cheque. I wouldn`t take any money to do that.
"I got a few offers to do Playboy actually. They want to pay you to be naked on the cover."
As well as refusing to posenaked for money, Rihanna - who is dating baseball star Matt Kemp - has previously admitted flashing her flesh in public would embarrass her mother.
She said in 2008: "I am only 20 so my mother would kill me if I posed nude! When I did that metallic body paint stuff for my video for `Umbrella`, I didn`t do it to show my body.
"I didn`t do it for people to like me. I did it because it was a cool visual, unexpected, and it looked hot."
While Rihanna doesn`t want to show off her body to other people, the 22-year-old star has previously spoken about her "obsession" with women`s breasts.
She said: "I grab boobies all the time, I`m obsessed. I don`t have much so anytime I see a good rack I`m like `Wow, I wish mine looked and felt like that.` Women are beautiful. I`m not into them but they are hot."
