In the late 1940s, Madan Mohan and Kishore Kumar sang as chorus boys for her songs at the Filmistan Studio. Begum promised at this time that she would sing songs composed by Mohan once he started his career as a music director and would accept a lower fee. She also predicted that Kumar would become a great playback singer. She later recorded duets with Kumar, including "Gori ke Nainon Mein Nindiya Bhari" from "Angarey" and "Mere Neendon Me Tum" from "Naya Andaz".
