Karan referred to section 377 of the Indian Penal Code, which criminalises homosexuality.
The 'Bombay Velvet' star, who produced the Tarun Mansukhani directorial, was asked by a fan on Twitter if he would make a sequel of 'Dostana', which unraveled a story of two men pretending to be a gay couple in order to secure an apartment.
"No! I will be stopped 377 times!" Karan quipped.
Is there a chance of seeing actress Deepika Padukone in Karan's Dharma Productions, asked another fan.
"Yeah, very soon!" he replied.
On the work front, the 'Student of the Year' helmer is currently busy shooting for his next film 'Ae Dil Hai Mushkil', which stars Ranbir Kapoor, Anushka Sharma and Aishwarya Rai Bachchan.
