The former Destiny`s Child singer - who is currently starring as a judge on the UK `X Factor` - enjoys visiting X-rated stores to purchase some raunchy products, but always makes sure she is discreet when she makes an adult shopping trip.
She said: "You can`t keep me away from a good sex shop. Those are interesting places. I go with a bunch of people - that way no one recognises me."
Kelly says she has become more "liberated" about sex since turning 30.
Talking about her latest single `Motivation` - which describes how she feels during sex and is included on her new album `Here I Am` - said: "I`m now liberated at 30, it`s almost a transition. I was scared what my mom would say after `Motivation` but she was yelling, `Go lover.` "
Kelly - who was once engaged to Roy Williams but the wedding was eventually called off - also says she has learnt not to take any "crap" when it comes to men.
She added to the Daily Mirror newspaper: "I wanted that wedding. I wanted to be married. I wanted to have kids. At that time I was crazily talking about wanting five. You can just make wrong decisions in life.
"That was all a part of growing up. I just think it`s important to trust your gut.
"I`m careful with my heart. I don`t take c**p from no one these days. I put my foot down. Being a woman you deserve heaven and earth. So if a man wants to date me, know that I don`t take c***p."
