Rihanna has admitted she loves to be 'tied up and spanked' in the bedroom.

The singer, whose latest single 'S&M' sparked controversy over its sexual lyrics, has said she is a sexual masochist.

"I think I'm a bit masochistic. I love feeling like I'm somebody's girl. I love to be tied up and spanked. Using whips and chains is too planned... you have to stop and look for the whip. I prefer them to use their hands," Rihanna told Rolling Stone.

She added: "I like to take the reins in my life, but I enjoy being submissive in the bedroom. In there I can be a little lady and have a male who has responsibility for the situation. That's sexy."
