Govinda was deeply unfaithful to his wife.
Despite getting engaged (and later married) at the time his career started in Bollywood he kept his marriage and child a secret for more than one year. During this time he had a storming affair with Neelam. He was almost ready to marry Neelam but Govinda's mother put her foot down. At one point Sunita and Govinda has regular fights over Neelam and Govinda decided to break off the engagement and told her to leave him. He even told Stardust magazine that if Sunita hadn't called him and coaxed him to come back he would have married Neelam. Interstingly he kept Neelam in dark about all this and introduced Sunita as his relative to Neelam!!
But he never really improved even after publicly recognising his marriage and child. Later on he had affair with Rani Mukherjee during the making of Had kar di aapne which again created tensions in his family.During that time, tabloids carried many gossip stories about celebrities, and it was reported that Govinda had gifted Rani many expensive items, including a luxury car and an apartment. Even recently when the news of Govinda's divorce were making the headlines and it was pointed out that Govinda and his wife are living separately, the fingers were pointed on Govinda for having an affair with a Marathi actress half her age.
In the early 90’s Govinda and his brother Kirti Kumar tried to launch a film Radha ka Sangam with Govinda and Divya Bharti. Govinda openly expressed his attraction towards Divya Bharti even though Kirti Kumar chucked her out of the film. They did worked in the film Jaan se Pyara.
Even in the chat with Kapil Sharma some time ago he and Shakti Kapoor agreed that they had affairs outside their marriage. He even shamelessly tried to defend his actions saying “Ek hi Life hai khul kar jiyo” (you have one life love it freely).
