She first gained attention in a supporting role as a vamp in the A grade color hit film Mere Sanam (1965). She gained major attention when she played one of Dilip Kumar's leading ladies in Ram Aur Shyam (1967). The film became one of the top hits of the year, and she received her first Filmfare nomination as Best Supporting Actress. She supported Sharmila Tagore in several films in the late 1960s, such as for Saawan Ki Ghata, Yeh Raat Phir Na Aayegi, and Mere Humdum Mere Dost. She had a memorable song and dance number "Aaj Kal Tere Mere" with her co-star Shammi Kapoor in the hit film Brahmachari (1968).
