Leonardo DiCaprio shared a humorous anecdote from the set of 'Once Upon a Time in Hollywood,' where Brad Pitt mistook DiCaprio's parents for extras. DiCaprio explained that his father is from a 1970s hippie counterculture background, and his stepmother is a Sikh. Pitt was surprised to learn they were DiCaprio's actual parents, given their distinctive style, which DiCaprio noted was how they dressed daily. The revelation about his stepmother's Sikh faith has also garnered significant attention from Indian fans.
