#WeDay Celebrations Begin In London With Prince Harry, Ellie Goulding and Jennifer Hudson (PICS)

The UK's first ever 'We Day' celebrations are well under way in London today.

Stars like Ellie Goulding, Jennifer Hudson and even royals like Prince Harry and Princess Beatrice have all come out to support the event at Wembley Arena, which youngsters could earn tickets to by committing to charitable acts.

The event was organised by the organisation Free The Children, and has already had great success in North America and Australia.

Other guests include businessman Richard Branson and UK singer Dizzee Rascal.
