Bono is due to meet with the six remaining finalists to talk with them about the work of ONE: The Campaign to Make Poverty History and how they and the show's audience can help in the fight against extreme poverty.
The 'Idol Gives Back' special will run over two nights in the US this week, Tuesday and Wednesday. Bono's chat with the finalists will feature briefly on the Wednesday evening show.
The special will raise money for Charity Projects Entertainment Fund (CPEF) and other organisations that help children and young people in extreme poverty.
