British singer LILY ALLEN has travelled deep into the Amazon rainforest to raise awareness about the endangered region.

The Smile hitmaker is spending a week in the Brazilian state of Acre filming a documentary for the World Wildlife Fund (WWF) charity in a bid to publicise the need for the rainforest's protection.

Allen is currently sleeping in a budget eco-friendly hut and is spending her time visiting a multi-million pound conservation project, which has been set up by the WWF.

The singer was also given a tour of the 'seringals' - where latex is harvested from trees before being taken to a factory to be turned into condoms.
