Film icon Kamal Haasan was left blushing during the inauguration of a retrospective of his films, when his partner Gauthami was referred to as Mrs Kamal Hassan on stage, in front of a packed audience.
S M Khan, the Director of Directorate of Film Festivals which organised the event, thanked "Mr Kamal Haasan and Mrs Kamal Haasan" for attending the event.
"They are not married and have always been very open about the nature of their relationship. The mistake rarely happens because everybody knows that they are not married," said a source close to the actor.
The Padmashri winning actor and director, however, later took the mic to wish Gauthami a very happy birthday and thanked her for accompanying him to the event.
Soni also congratulated the actress on her birthday, thanking her for taking out time to be at the event.
Haasan and Gauthami have been together for the past three years after the actor split from his wife Sarika in 2002.
Kamal's two daughters with Sarika, Shruthi and Akshara often make public appearances with Gauthami.
