Actor Orlando Bloom, will be spearheading a campaign to improve the education standards of the poor children in Madagascar, in Africa. The Pirates of the Carribbean star, who is also a UNICEF Goodwill Ambassador, is coming together with actress Sienna Miller, for the BOSS Orange Education Campaign for UNICEF.

Reports state that every purchase of the limited edition fragrance from the company, will help in funding a day of school for 50 underprivileged children. Talking about this, Bloom says, "I feel very privileged to be working with BOSS Orange and UNICEF on this partnership. Witnessing first-hand, the difference it makes to the lives of children in Africa is truly humbling."

Looks like working for humane causes runs in the family, as Miranda Kerr, Bloom's wife, has signed up as a global ambassador for Earth Hour 2012, which encourages the public to switch off all their lights for 60 minutes on March 31, to conserve energy.
