When ace lensman Dabboo Ratnani calls, Bollywood always turns up. And why not, seeing how the photographer has immortalized the stars in his famous calendars.

The launch of Ratnani's 2010 calendar kicked off to a glittering start on Wednesday as well.

Among the attendees spotted at the event is Shah Rukh Khan, who posed under his own picture.

Vidya Balan appeared quite bold in her topless picture for the calendar. Quite a contrast from the sari-clad look the actress wore to the launch.

Unlike the previous years, Hrithik Roshan did not show off his sexy torso in the calendar. Instead, he showed off his curls.

Genelia D'Souza chose to pose with the man of the moment himself -- Dabboo Ratnani.

Minissha Lamba was also spotted at the event.

It's not what you think. But Shahid Kapoor and Genelia, did spend the night together in the cramped confines of a car to promote their film Chance Pe Dance on Wednesday night.

The two play strugglers in the Ken Ghosh-directed film. At one point in the film, Shahid's character has to live in his car. Hence, the sleepover where Shahid and Genelia slept in the car from midnight till day break.

Shah Rukh Khan poses with Hyundai's 'i 10 electric' car at India's Auto Expo in New Delhi on Wednesday. The trade show runs from January 5 to 11.

Elsewhere in Mumbai, Salman Khan was promoting his upcoming movie Veer at Big FM studios. The film will release on January 22.
