Before Emma Watson helped launch the 'HeForShe' campaign with the UN Entity for Gender Equality and the Empowerment of Women in 2014, what did you know of the agency?
We presume, not a lot.
But since the agency brought on the 26 year-old as a goodwill ambassador, there has been a bevvy of celebrities eager to work with the intergovernmental organisation.
According to Maher Nasser, the Director of the Outreach Division in the UN's Department of Public Information, given the rise in awareness of Watson's work with the UN, he is now regularly having to turn down publicists calling to show famous celebrities' interests in becoming a goodwill ambassador.
'We do say no,' he told The Times.
Watson's debut speech in 2014 resulted in unprecedented views on the UN's YouTube channel currently amounting to over 7million. 'Usually we get a few thousand,' Masser revealed soon after Watson's passionate speech regarding sexual violence and gender parity on university campuses, earlier this week.
In light of the actress' continued success as a representative of the UN, we've rounded up a list of A-list celebrities we think could make the cut to become UN goodwill ambassadors:
The actress speaks English, French and German fluently and is regularly seen helping out those in need. She's urged people to share stories relating to Syrian refugees and this weekend, the 39-year-old volunteered with the charity God Loves NYC to make 3,600 meals for hopeless people around New York City.
Last year, the Victoria Secrets supermodel launched the Kode with Karlie scholarship, a charity that offers a two-week full-time course in computer programming used in many apps.
She's also volunteered alongside Christy Turlington in Haiti for the nonprofit organization, Every Mother Counts which seeks to educate the world about issues facing women.
The philanthropic chef launched the Jamie Oliver Foundation (previously known as the Fifteen Foundation) – in 2002 to help disadvantaged and troubled teenagers become professional chefs.
He's also launched a global petition to get practical food education on the school curriculum as part of his Food Revolution campaign and has spoken on numerous occasions about the importance of teaching children how to eat healthily.
The British actor has regularly been seen volunteering at charity and political events, including for CalAid to urge Londoners to donate and volunteer to provide assistance to refugees and migrants in Calais.
He's also been spotted visiting patients at the University College Hospital London.
Actress Olivia Wilde has volunteered in morgues in Haiti and traveled to Senegal to report on the progress of health workers using mobile apps to help fellow citizens. She is also an advocate for feminism and gay rights.
The model is a long-term supporter of Unicef UK and recently visited Lesotho to meet and talk with families and children affected by droughts, poverty and HIV.
The 23-year-old Star Wars actor has been spotted delivering toys to sick children at The Royal London Hospital, on behalf of the Rays of Sunshine children's charity.
He also nominated the Damilola Taylor Trust to receive a donation from the launch of the new Star Wars film The Force Awakens.
For her 18th birthday, the model refused to accept gifts, insisting people donate toys to charity instead. And last year, the 20-year-old sold her old clothes and accessories on eBay to raise money for the Children's Hospital Los Angeles.
She also recently featured on The Black Eyed Peas' re-release of the song 'Where Is The Love?', with each purchase going to will.i.am's i.am.angel foundation to help fund educational programs and college scholarships in the US.
Good work, Emma.
