Blanchett, 46,met Charu backstage during her visit here to be a part of 'Women in the World' summit.
"Charu, an extraordinary make-up artist, while she was applying lipstick to me, told me how she challenged the... (ongoing practice) in Supreme Court that women cannot be make-up artists in Bollywood.
"She won the right to be a make-up artist and already, 400 women have become make-up artists in her way," the actress said.
