Katy Perry has been appointed as UNICEF's newest Goodwill Ambassador.
The 'Roar' singer will work with vulnerable young people to help them take an active role in securing a "brighter future" for themselves.
She will work with children and adolescents living in severe poverty, affected by violence, abuse, and neglect, and in emergency and conflict situations.
Perry said: "I believe young people have the power to change their own lives, with our help.
"I am honored to join UNICEF as a Goodwill Ambassador, and committed to doing everything I can to help children and adolescents who come from such different backgrounds but want the same thing: a brighter future."
Anthony Luke, UNICEF Executive Director, added: "Katy Perry is already a champion for children, and we look forward to hearing her 'roar' on behalf of UNICEF.
"We are delighted that she is joining us as UNICEF's newest Goodwill Ambassador and lending her remarkable voice to amplify the voices of children and young people around the world."
Earlier this year, the Prism star visited Madagascar as part of a UNICEF mission, bringing attention to the situation of children living in the country.
As a UNICEF Goodwill Ambassador, she follows in the footsteps of David Beckham, Orlando Bloom, Jackie Chan, Liam Neeson, Susan Sarandon and more
