Katy Perry appointed newest Goodwill Ambassador with UNICEFListen /
Pop superstar Katy Perry was on Tuesday appointed the latest Goodwill Ambassador of the UN Children's Fund (UNICEF).
The American singer will focus on engaging young people in the agency's work to improve the lives of the world's most vulnerable children and adolescents.
Besides being one of the world's top selling recording artists, Katy Perry has more than 48 million followers on Twitter.
She says she will use this "big spotlight" to promote things that matter.
"I can get people interacting about UNICEF, about specific areas, people in need, children in need. We can pinpoint if there are various places that we need to focus on more than others. Whenever there is a crisis going on I can always kind of call up my troops. And I think they respond because I think the people that resonate with my music have the same hearts too."
Katy Perry recently called on her social media "troops" to support UNICEF emergency efforts for children, including those affected by Typhoon Haiyan in the Philippines.
Her hit song 'Roar' was used in a Public Service Announcement for the International Day of the Girl Child, observed on 11 October.
