Singer-turned-fashion designer Victoria Beckham is reportedly going to become an ambassador for United Nations campaign UNAIDS.

Beckham will work with the UN as a goodwill ambassador for their initiative after being inspired by a recent trip to South Africa, where she met with children stricken by the deadly disease, reports femalefirst.co.uk.

A friend of the star told The Sun newspaper: "She wants to give back by doing what she can."

Beckham, who has children Brooklyn, 15, Romeo, 11, Cruz, 9, and two-year-old Harper - visited Cape Town in February as part of the Born Free initiative, which tackles the issue of HIV being transmitted from mothers to their children.
