yes it was rumored that hina rizvi the so called younger sister of kavita is daughter of asif raza mir, but some say hina rizvi is from some other wedding of kavita rather than asif raza mir.
Asif Raza mir son of renowned director Raza Mir had a brief filmi career, during which he had an affair with Sangeeta sister Kavita, she was desperate to marry him and settle down to escape her Dalal mother Mehtaz Bano and Tayyab Rizvi, It is rumoured she had a daughter from him, But Asif's father totally opposed this marriage, and later in 1992 he married a garailoo woman named Sumra Farooq, poor Kavita!
Well it was not wedding, actually her midwife mother, Mehtab Bano even though not from Heera Mandi was immensely business minded woman that surprised the guardians of the actresses of Heera Mandi, she cashed on her daughters so well, Kavita was given in the harem of a fake pir, Hina Rizvi is the outcome of such a liaison!
