Sanjay Dutt has always been known for his spontaneous generosity. There are many in the industry who have benefited from it and can bear witness to that. Recently, the actor made another one of his generous gestures when he agreed to make an appearance in Vashu Bhagnani's son's launch movie.

According to reports, Dutt made an appearance in the title track of his son Jacky Bhagnani's launch movie, Kal Kissne Dekha. The actor, in a further show of generosity even refused take a penny from Bhagnani for the song. The incident took place in South Africa's Cape Town, where Bhagnani was shooting for his movie and Dutt was there for the shooting of Chatur Singh Two Star. It seems that Vashu and Jacky dropped in on Dutt's shoot and invited him over to theirs. One thing led to another, and when Jacky confessed that he was a big fan and would love to share screen space with him, large hearted Dutt agreed instantly to take part in the title track. He carved time out of his schedule for Chatur Singh and shot for the song, in which he plays a DJ. Vashu and Sanju worked together four years ago in Shaadi No 1. Kal Kisne Dekha is being directed by Vivek Sharma of Bhoothnath fame. Besides Jackky, the film will also be launching the late Manmohan Desai's grandaughter Vaishali Desai.
