Her powerful speech on International Women's Day last month - calling for equal rights for all women and girls - received global praise.
But now Hollywood star and UN Goodwill Ambassador Nicole Kidman is facing questions about her own commitment to women's rights, after endorsing an airline accused over the alleged mistreatment of its female staff.
In an open letter, the 25,000 member strong Association of Professional Flight Attendants (APFA) addressed the actress directly, urging her to end her involvement with United Arab Emirates-based Etihad Airways.
Laura Glading, national president of the APFA said: "We urge you, on behalf of the women and girls that you spoke to so eloquently, not to play a part in promoting Eithad Airways, a company that imposes abusive labour practices on its female employees and whose sole owner is a government that stands against the very world that you imagine".
The letter, which praises the star for her work promoting women's rights, goes on to say: "Sadly, Etihad's abhorrent labor policies are hardly surprising when one considers the fact that the airline is wholly owned by the UAE, a country where the only thing that is being 'stepped up' for women and girls is the level of abuse".
