Rumors have run rampant that Rihanna underwent plastic surgery to increase the size of her bust. Yet, Rihanna is denying she has had any work. ?I?m terrified of going under the knife. Because of the pain, the complications – not to mention the fact that it?s utterly unauthentic. If my t*ts aren?t feeling big one day, too bad. I?ll get a good bra. I like my body and I work out as hard as I can to make it as perfect as possible. But at the end of the day there?s always people who criticize your weight, your hairstyle and what you?re wearing. I just get on with it.?
