Priyanka Chopra might be entering into every possible field but it looks like the actress does not have complete knowledge about everything she does, especially football. Talking about her first part in the American culture, the 33-year-old actress said that she sang the 'Sunday Night Football' theme song for two years in a row, although she still doesn't know anything about American football. The 'Mary Kom' star further added that she has got no time to take up her musical career as she has to visit India after every few days because of her film ' Bajirao Mastani.'
