British actress and UN Women Global Goodwill Ambassador Emma Watson will host a special event in London in occasion of International Women's Day, which falls on 8 March.
The aim of the campaign is to engage men and boys in removing the social and cultural barriers that prevent women and girls' full participation in society.
Watson's fans have the chance to attend the event by submitting a story on how they contributed to advancing gender equality, accompanied by one or two photos or a short video.
UN Women will then select the individuals who will become audience members.
Watson posted a video on Facebook announcing the HeForShe event in London.
"Thank you so much for all your support and participation so far. It's been an absolutely amazing journey for me," she said in the video.
