British actor Orlando Bloom is to be a goodwill ambassador for the UN children's organisation Unicef.

Unicef said the star of Lord Of The Rings and Pirates Of The Caribbean would work to help poor children and raise awareness of the organisation.

The 32-year-old's first task will be to film an appeal about the importance of clean water supplies.

Past ambassadors include David Beckham, Audrey Hepburn, Roger Moore, Vanessa Redgrave, Shakira and Ryan Giggs.

Bloom, regarded as one of the world's most popular male celebrities, said he wanted to be an active ambassador for Unicef.
