Stars including Ellie Goulding, Dizzee Rascall and Jennifer Hudson are already beginning to arrive for today's #WeDay at London's Wembley Arena - and you can watch all of the action on - and off - stage right here with our live feed.
And keep 'em peeled for Prince Harry too, who will be giving a motivational speech alongside Malala Yousafzai and Al Gore .
The event - hosted by MTV’s Laura Whitmore, Bluey Robinson and Lilah Parsons - has already had great success in North America and Australia, with its theme of global empowerment.
Tickets are not available for purchase, instead, Year 6 students must commit to undertake at least one local and one global act as part of the We Act programme in order to gain access to the Wembley Arena event.
