Russell Brand, Simon Pegg and Steve Coogan are the latest British celebrities to back a social media campaign to raise money for a cancer charity.

The stars have thrown their support behind the #ThumbsUpForStephen social media fundraiser in honour of Stephen Sutton, a British teenager suffering from incurable cancer, who drew up a bucket list which included a wish to raise $1.6 million (£1 million) for the Teenage Cancer Trust.

His story hit headlines this week (beg21Apr14) after the 19 year old wrote a heartfelt message on Facebook.com, and a number of celebrities have now backed his fundraising efforts, posting images of themselves holding a piece of paper which encourages fans to donate to the campaign via text message.

Sutton's goal was reached on Tuesday (22Apr14). The campaign total had hit $2.7 million (£1.7 million) when Wenn went to press.
