Actor Varun Dhawan took off his shirt for celebrity photographer Dabboo Ratnani's 2013 calendar, but the Bollywood newcomer says he wouldn't do it again.

"He (Dabboo) only said, 'You can take off your shirt, and everyone is doing it'. But I can't do it again because my mom gets really angry," the 24-year-old said here Tuesday at the calendar launch.

Meanwhile, Varun said it was a great honour to shoot with a veteran like Ratnani, who has been releasing a celebrity calendar annually since 14 years.

"It was a great experience because Dabbooji is in this line for such a long time and so many actors have worked with him. It is a big thing for me because I have done just one film," said the actor, who made his debut with "Student Of The Year".

Shah Rukh Khan, Arjun Rampal, Vidya Balan, Hrithik Roshan, Alia Bhatt, Varun Dhawan, Madhoo and a host of other Bollywood celebrities attended the launch of the new calendar.
