We all know that Raju Hirani’s 3 Idiots stars Aamir Khan, Madhavan and Sharman Joshi. There is also Kareena Kapoor in the film. 
What we don’t know is that the film has three kisses as well that Hirani was not keen to publicise until the film’s launch date. All three kisses are between Aamir and Kareena, naturally. 

It can be recalled that Aamir, incidentally, famously kissed Kareena’s elder sister Karisma Kapoor in Dharmesh Darshan’s 1996 film, Raja Hindustani — a kiss that still holds the record for being one of the most passionate in Bollywood history. For that scene Aamir and Karisma had reportedly done umpteen rehearsals.

The actor continues to be a perfectionist with exacting standards. For a scene in 3 Idiots where Kareena blows him a kiss, they apparently did 14 retakes. That was Kiss No. 1. Aamir improvised then and got Bebo to kiss him on the cheek next. And that was Kiss No. 2. But it’s Kiss No. 3 between the two superstars in the climax of the film over which the buzz has already begun. It’s believed to be a proper lip-to-lip kiss. 
3 Idiots is one of the most eagerly awaited films of the year and is all set to release during Christmas.
