Celebrities have joined friends and family of teenage cancer fundraiser Stephen Sutton in two special online campaigns marking one year to the day since his death - and, keeping true to his legacy, raising money for charity.
The hashtag #hugforstephen has been used by celebs including Stacey Soloman, Nadia Sawalha, Gaby Roslin and Linda Robson, encouraging people to post a 'hugging' picture to Twitter and donate £2 to charity Fixers.
And supporters are also urged to post their own #ThumbsUpForStephen selfies at 11am and donate £1 to the Teenage Cancer Trust.
Fixers helps young people campaign for issues which matter to them, while the Teenage Cancer Trust was Stephen's charity of choice.
Stephen died last year at the age of 19, having fought for years against bowel cancer.
His story caught the imagination of the general public when he posted what he believed would be his "final thumbs up" in January.
People around the world were moved by his good humour and generosity, and donations began flooding in to help him reach his 'bucket list' goal of raising £10,000 for the Teenage Cancer Trust.
He upped his aim to £1 million as cash continued to pour in, but soon smashed this target too. Eventually, he helped raise more than £5m for the cause.
The outpouring of support seemed to give his health a boost, and - in a turnaround which left doctors baffled - he was even able to return home for a short time before he was forced to return to hospital, where he finally succumbed to the disease.
