Simon Pegg, Ricky Gervais and Barry Manilow have joined British Prime Minister David Cameron in mourning the death of a brave teenager who lost a battle with cancer after raising millions for charity. Brit Stephen Sutton, 19, brought in more than $5.1 million (£3.2 million) for the Teenage Cancer Trust by launching an online campaign after he was given a terminal diagnosis by doctors. He died in his sleep in the early hours of Wednesday morning (14May14), and a number of high-profile stars offered their condolences following his passing. Star Trek actor Pegg writes in a post on Twitter.com, "Very sorry to hear about the passing of Stephen Sutton. A brave young man who raised a lot of money for cancer research, despite everything," while funnyman Gervais adds, "RIP Stephen Sutton. A true hero & inspiration to us all." Manilow calls him a "hero" and an "inspiring and beautiful soul", while British pop rockers Lawson, who donated the proceeds from one of their gigs to Sutton's fundraising effort, write, "So saddened to hear of (Sutton's) passing but so inspired by the difference he made. You can still donate." British leader Cameron adds in a statement, "I'm deeply saddened to hear that Stephen Sutton has died. His spirit, bravery and fundraising for cancer research were all an inspiration."
