Now, an interesting discussion has been happening in Tollywood circles and this is about the costliest navel in Tollywood. Well it is heard that this belongs only to one girl and she is Samantha. Apparently, Samantha was spotted with her navel pierced in few film related events. Sources say she has filled her navel with a diamond belly button. Buzz is that the price of the diamond is more than Rs 1 lakh. She put it in her navel and maybe that’s why ‘Dookudu’ became a blockbuster and Samantha has bagged big projects.
