Singers Jennifer Hudson and Ellie Goulding performed at a youth empowerment event in London on Friday (07Mar14) to thank youngsters for their charity work. The inaugural U.K. concert at Wembley Arena was held to celebrate and promote kindness by young Brits, and all 12,000 guests had earned their ticket by completing acts of local and global service. Goulding and Hudson thrilled revellers alongside other stars including rapper Dizzee Rascal and British singer/songwriter Birdy, and the entertainment was broken up by inspirational speeches from public figures such as tycoon Sir Richard Branson and former U.S. Vice President Al Gore. Goulding wrote on Twitter.com ahead of the show, "Today I am delighted and honoured to perform at We day. Inspiring today's youth to change the world." Prince Harry also delivered a speech at the event, while casually dressed in a shirt and jeans, and he began by cracking a joke: "You were probably hoping for Harry Styles so I'm sorry to disappoint you - no, I'm not going to sing!" Harry's girlfriend Cressida Bonas, his cousin Princess Beatrice, and U.S. TV actors Jacob Artist and Shay Mitchell also attended the daytime event.
