Katie Holmes is to become the ambassador of Tommy Hilfiger's new collection. The stunning actress has teamed up with the designer to promote The Promise Collection, which is part of Hilfiger's role as a Millennium Development Goal global leader.

The collection - which features pieces that have been either been produced in Africa or that use locally-sourced cotton - comprises classic Tommy Hilfiger styles but in a bold color palette featuring vibrant African prints. All profits from the range - which will be sold in Tommy Hilfiger stores worldwide as well as online from late April - will be invested back into Millennium Promise, the charity set up to help achieve the Millennium Development Goals, including to halve extreme poverty by 2015.

Hilfiger has already visited Ruhiira in Uganda to see the difference his $2 million donation in 2010 made, while Katie has also visited the rural region, ahead of fronting the campaign. In the campaign, there will be a focus on women's issues by the charity - including working towards gender equality, maternal health and universal education.
