Will.i.am stressed the importance of nurturing creativity from young people from inner cities today, as he donated £500,000 to the Prince's Trust. He said there was a large resource of musical creativity around London that should be channelled to build work skills.
"I grew up in east Los Angeles, one of the most under-served and tough neighbourhoods in America. My family made sure I understood that getting a good education and hard work were key to turning my dreams into reality and beating the odds that come with growing up in a disadvantaged situation."
"The Prince's Trust has a 36-year history of assisting disadvantaged youth, so I am pleased to be collaborating with an organisation that shares my mission to transform the lives of young people who need extra support and structure in their lives."

After hearing the news Hannah, from Chepstow, nodded before hugging Max and saying: "This has probably been the best year of my life, I turned twenty one, I've sung for the Queen, I've done live television. I know what I'm doing with my life."
Ruth Ann looked dejected when she heard the news, saying: "It's been a crazy rollercoaster doing this show, I've learned so much from Jessie - in fact from all of you guys, some of the comments you've made and said to me have been life changing. This is not the end."
The Voice star Matt Fletcher has revealed he refused to bow to pressure from BBC bosses to shave his beard because he feels it is the source of his power.
He said: "They were talking about taking off the whole beard, but it's a part of me and I lose my power without it."
He added: "They did try and I said something like 'I think I could take two or three of you down before you pin me down and shave it, but if you want to go for it, go for it', and they backed off."
Simon Cowell appears to have conceded defeat to BBC's The Voice in last night's prime time TV ratings war.
The BBC talent show drew in four million more viewers than Britain's Got Talent's six million when the two shows overlapped for 20 minutes from 8pm.
A slightly irritated congrats to Danny and the BBC. But you didn’t have a dancing dog!
But Cowell has taken consolation in the super-popular dancing dog on the ITV1 show and says he's still "loving the show this year."
I thought our team made a fantastic show last night and congrats to them as well. Loving the show this year. @gottalent
