Katy Perry has visited Madagascar in aid of UNICEF.

The 'Part Of Me' singer jetted out to the Indian island last Tuesday (02.04.13) to raise awareness of the current situation in one of the poorest countries in the world, with the help of The United Nations Children's Fund.

Katy, 28, viewed a variety of programmes highlighting the problems, including education, nutrition, health and child protection to water, sanitation and hygiene.

Her first stop was a slum in the capital of Antananarivo, where she stopped by a child protection centre to see how they help support abandoned and abused children and young mothers.

Speaking about her experience, Katy said in a statement: ''In less than one week here in Madagascar, I went from crowded city slums to the most remote villages and my eyes were widely opened by the incredible need for a healthy life - nutrition, sanitation, and protection against rape and abuse - which UNICEF are stepping in to help provide.

''I am grateful to UNICEF for giving me the opportunity to see first-hand how their programmes make a real difference in children's lives. Support for UNICEF is saving children, I am a witness to it.''

The stunning star - who recently split from musician John Mayer - told her followers on Twitter about her trip on the day she left, writing: ''Heading to AFRICA tonight, no joke. (sic)'', accompanied with a video titled 'Crazy Intense Lemer'.

She also shared her own realisations of how ''different'' she finds life in the poverty stricken land.

She joked: ''I just watched what looked like a 7 year old girl make her own marmite sandwich. #differentplacesdifferenttastes (sic)''
