Singer Mika Singh revealed he once gatecrashed actor Amitabh Bachchan's Diwali party. "Every year, Amitabh would celebrate Diwali at his house and I would pass by and admire all the decorations," the 47-year-old said. "I had a big car, a Hummer, so I entered his house without an invitation once. I took a couple of rounds and exited," Mika added.
