Shammi Kapoor and Mumtaz were linked with each other when they worked together in 'Brahmachari'. Infact, at several occasions, and even very recently, Mumtaz had revealed that Shammi wanted to marry her but she refused him as there was a trend in the Kapoor family that their daughter-in-laws do not work in movies. Thus, she had refused his offer to marry. While Mumtaz has spoken about Shammi at several instances, in a very rare interview, Shammi had also admitted to being in a relationship with Mumtaz.
During a chat with Lehren Retro, Shammi Kapoor was asked about his film 'Brahmachari' and later, the question moved to Mumtaz. Reacting to it, Shammi said, "Mumtaz was a very beautiful thing in that movie. I was a widower and Mumtaz happened to be a very pretty little girl. For a short while, we both had dreams but then it turned into a nightmare. So, it's fine. I am happy as I am today."
For those not in the know, Shammi was married to Geeta Bali but she passed away leaving a huge void in his life. He later married Neila Devi.
In an earlier interview with Etimes, Mumtaz had said, "Shammi Kapoor was really sweet and compassionate with me, Nobody could hardly think we were in love. Nobody thought I had turned him down for marriage since Shammi's financial standing was better; they questioned, How can Mumtaz deny Shammi?”
The actress had also said that she wanted to marry him. "There was a rule, that ghar ki bahu kaam nahi karegi. It was as straightforward as that.” Mumtaz had said that this rule was made by "Papaji" and by that she meant Prithviraj Kapoor.
