The "Umbrella" singer - who begins her series of concerts in December - is keen to wow fans with her revealing S+M-themed costumes and raunchy dance routines.
She told Britain's Daily Star newspaper: "The tour is going to be very rock star, very sexy with a dominatrix theme."
"I'm very involved with the creative process. We have been busy planning, coming up with costume ideas."
Rihanna refuses to be sidelined during the organization of the shows, saying: "I have professionals who guide me, but I like to know what's going on and make suggestions that we collaborate on."
The 19-year-old star also revealed she is being lined up to launch her own clothing range.
She said: "I can' say any brand names until the deal is signed, but it's happening."
Meanwhile, Rihanna has lent her support to troubled star Amy Winehouse.
She believes Amy, who was recently hospitalized after a drugs overdose, will recover and become a big success in America.
She said: "I'm worried about Amy. I want her to get better as I love her. There's no doubt in my mind she can still be successful in America even though she's been linked to drugs."
"It'd be awesome to go on tour with her in the States. I'd love her to join me."
