Why did Deepika skip the tattoo convention she was invited too?

                                   Deepika Padukone was invited to attend a tattoo convention held in Mumbai on Sunday but she skipped the event, playing the 'busy' card. Incidentally, Dippy sports not one but two tats the 'RK' print on her neck and an anklet on her foot. The organiser of the event says, "Deepika Padukone's absence was felt, especially at an event that she would have readily identified with. With her own much-written-about RK inking at the base of her neck and the Dum Maaro Dum tattoo she's seen sporting in the movie, she would have been the perfect ambassador for the expo."
