/> Shah Rukh's generosity of spirit doesn't only stretch to giving away watches on KBC. He knows how to repay old debts. And producer Viveik Vaswani found that out recently when he approached the Khan to make a guest appearance in his new production Dulha Mil Gaya.

Not only did SRK readily agree to make an appearance in the comedy he has also agreed to let his role be extended to more than double what it was meant to be originally.

This isn't the first cameo appearance SRK has done for a friend. Recently he made fleeting appearances in Silsilay, Kuch Meetha Ho Jaye and I See You.

"These were for friends. And although I don't like making cameo appearances I can't say no to a friend if he asks me to be in his film. Viveik is someone I've known from the time I came to Mumbai. And yes, he requires more of my dates for his film. So why not?" reasons SRK.
