Soha Ali Khan had share the same screen with her mom Sharmila Tagore for a TV Commercial. And now they will soon share big screen in Aparna Sen's next flick. She is happy and nervous at the same time working with mom. "Mom's such a professional and natural. She has seen every work of mine to date, and discussed each of it in great detail with me; praising me when I deserve praise and correcting me in places where I could've done better," she explains.
