The 38-year-old businessman has plastered every square inch of his house with Khan's pictures and spent his honeymoon waiting outside the actor's house in Mumbai, hoping to catch a glimpse of his idol.
"I will do anything that will make Shah Rukh Khan happy," Singh, who runs a homeopathic medicine business from Lucknow, told Reuters.
Singh's house is a shrine to Khan. There are cut-outs of Khan on the ceiling, the television and even on cushions. Singh has even changed his name to Vishahrukh Khan.
"No one can be like Shah Rukh Khan, but I wanted my name to have his name. My children are named Simran and Aryan, which is his son's name," he said. Simran is the female lead in one of Khan's biggest movies.
His family was initially less than impressed with his adoration of the star, Singh said.
"My parents were very worried about me, but now they know that my love for Shah Rukh will never end," he added.
Khan has met his fan several times, including on Singh's honeymoon, when Singh drove more than 1,300 km (810 miles) with his wife to Mumbai. Khan has not returned the favour as yet, even though he's promised to visit Singh's home.
"I've been wanting to open up a store of homeopathic medicines, but I won't open it until Shah Rukh comes and cuts the ribbon," he said.
Khan, 46, is one of India's most revered stars, and his latest film, "Ra.One", opened to packed houses during the Diwali festival last week. Singh will watch the movie for the fourth time in a week on Wednesday, which is Khan's birthday.
"We'll cut a cake, dance and watch the movie. We'll celebrate our love for him," he said.
