UNICEF ambassadors Millie Bobby Brown, David Beckham, P!nk, Chloe X Halle, and Sachin Tendulkar are among the many stars supporting World Children's Day on November 20.

The date marks the anniversary of the adoption of the Convention on the Rights of the Child, and the mobilisation of the first World Children’s Day. Stranger Things star Brown, 13, commented 'I am so excited for the first ever global celebration of World Children’s Day on November 20th with UNICEF. It’s our day, everyone! A day for us to raise our voices and unite. So let’s do it - in our schools, with our friends, with our families!'. Beckham also stars in a #KidsTakeover campaign video, in which he asks five children about what changes they would like to see for children in the future, and what rules they would make for grown-ups.
