actress Ruma Guha Thakurta aka Ruma Ghosh. Their marriage lasted from 1950 to 1958. Kumar's relationship with actress Madhubala was the subject of much media attention. Madhubala had worked with Kumar in many films including his home production Chalti Ka Naam Gaadi (1958) and Jhumroo (1961). According to Madhubala's sister Madhur Bhushan, after Madhubala's relationship with actor Dilip Kumar faded, Madhubala got involved with Kishore who was going through a divorce with Ruma Guha Thakurta. Their love affair went on for three years through Chalti Ka Naam Gaadi and Half Ticket. Madhubala was ill and was planning to go to London for treatment. She had a ventricular septal defect (hole in the heart). The couple had a civil wedding in 1960 and Kumar reportedly converted to Islam and changed his name to Karim Abdul. His parents refused to attend the ceremony. The couple also had a Hindu ceremony to please Kumar's parents. Their marriage ended with Madhubala's death on 23 February 1969. Kumar's third marriage was to Yogeeta Bali, and lasted from 1976 to 4 August 1978. Kumar was married to Leena Chandavarkar from 1980 until his death. He had two sons, Amit Kumar with Ruma, and Sumit Kumar with Leena Chandavarkar. Kumar is said to have been paranoid about not being paid. During recordings, he would sing only after his secretary confirmed that the producer had made the payment. On one occasion, when he discovered that his dues had not been fully paid, he appeared on set with makeup on only one side of his face. When the director questioned him, he replied "Aadha paisa to aadha make-up." (Half make-up for half payment). On the sets of Bhai Bhai, Kumar refused to act because the director M. V. Raman owed him 5,000. Ashok Kumar persuaded him to do the scene but when the shooting started, Kishore walked a few paces and said, Paanch Hazaar Rupaiya (five thousand rupees) and did a somersault. After he reached the end of the floor, he left the studio. On another occasion, when producer R.C. Talwar did not pay his dues in spite of repeated reminders, Kumar arrived at Talwar's residence shouting "Hey Talwar, de de mere aath hazaar" ("Hey Talwar, give me my eight thousand") every morning until Talwar paid up. In spite of his "no money, no work" principle, sometimes Kumar recorded free even when the producers were willing to pay. Such
