Following Emma Watson's nerve-tingling speech at the UN earlier this week, where she called on men and boys to support gender equality as part of the #HeForShe campaign, many celebrities have come out in force to support her and out themselves as feminists.
From Joseph Gordon-Levitt and Douglas Booth to Forrest Whittaker and Simon Pegg, many of these supporters are male - refreshing given that feminism is often, as Emma points out, associated with 'man-hating'.
“I decided I was a feminist and this seemed uncomplicated to me,” she said. “But my recent research has shown me that feminism has become an unpopular word.
“Apparently I am among the ranks of women whose expressions are seen as too strong, too aggressive, isolating, anti-men and, unattractive. Why is the word such an uncomfortable one?”
She added: "For the record, feminism by definition is: 'The belief that men and women should have equal rights and opportunities. It is the theory of the political, economic and social equality of the sexes.'"
Emma was appointed as the UN Women Goodwill Ambassador six months ago, but in her speech, she said she first became aware of sexism at the age of eight, when she was called "bossy" for wanting to direct school plays - her male classmates were not described in the same way.
"At 14 I started being sexualized by certain elements of the press. At 15 my girlfriends started dropping out of their sports teams because they didn’t want to appear muscly," she added.
As well as pointing out the discrimination women often face, Emma refreshingly highlighted that men can suffer because of gender inequality too.
Here are just a few of the celebrities joining Emma and the UN's #HeForShe campaign.
