Katy Perry takes on Unicef role

Pop star Katy Perry said becoming a goodwill ambassador for the UN children’s agency has made her realise that there is more to happiness than material possessions and social status.

She said that on her first trip for Unicef, to the impoverished Indian Ocean island nation of Madagascar in April, she was moved by “the incredible joy” of the children despite the difficulties many faced – and that inspired her to write the song Unconditionally.
