Katrina Kaif is supporting a noble cause that is being looked after by her mother Suzanne. The actress has in fact signed up the Oscar winner AR Rahman to compose music for a video that will be used to raise funds in support of the cause. Katrina, apart from donating Rs. 50 lakhs, will also star in the video.

The funds, according to our sources, will be used to inaugurate the children’s wing adjacent to Mercy Home in Chennai.
