The 27-year-old star said the people's need to show off that they have fame leads to a wastage of energy and time, reported FemaleFirst.
"It's like an incessant mosquito noise. Very weird. People feeling the need not only to judge everyone all the time but also to pronounce themselves on it, it's extremely boring. A waste of energy and time," Johnson told Spain's Vogue magazine.
The "Fifty Shades Darker" actor has previously said that despite her fame, she rarely gets recognised in public.
