I know there seem to be ribbons for all sorts of charities and causes, but this one is a great one! Celebrities and pop stars rubbed shoulders tonight at an event promoting safe motherhood.

BBC presenter Tess Daly, Prime Minister's wife Sarah Brown and singer Annie Lennox were among the celebrity guests attending the White Ribbon Alliance's Global Dinner Party Campaign.

The White Ribbon Alliance for Safe Motherhood is an international coalition to promote increased public awareness of the need to make pregnancy and childbirth safe for all women and newborns.

The Alliance is asking people around the world to wear white and hold a dinner party this month for the 100th year of International Women's Day on March 8.

The white ribbon is dedicated to the memory of all women who have died in pregnancy and childbirth.
