His positivity just shone through.
Nineteen-year-old Stephen Sutton inspired the nation with his brave battle with terminal cancer. Shortly after being given the news that his condition was incurable, Stephen set-up a Facebook Page called Stephen's Story.
Initially a bucket list of his ambitions, it soon went viral attracting celebrity support from the likes of Jason Manford and Jimmy Carr, Stephen then decided to focus on raising money and awareness of cancer in Teenagers and Young adults. His initial goal was to raise £10,000, by the time he passed away on 14 May 2014 he'd raised over £3 million. On Sunday his mum Jane ran the London Marathon and she joins us today to talk to us about continuing Stephen's legacy.
With over 22 years gracing our screens, she's won legions of fans fronting Big Brother, reunited estranged relatives on Long Lost Family and got the national feeling fit and healthy with her top-selling fitness DVDs and cookbook.
But how will Davina McCall shape up as she takes on her ultimate challenge - becoming the guest editor of This Morning? It's time to find out!
On Saturday a devastating earthquake measuring a magnitude of 7.8 hit Nepal.
More than 3,200 people were killed in what was the worst earthquake to strike the country in more than 80 years. The earthquake triggered avalanches on Mount Everest, killing at least 17 people, injuring many more and leaving climbers further up the mountain in peril.
Amanda's sister Debbie is out in Nepal, and we're hoping to speak to her on the phone today. We're also joined by Alex Parry, whose girlfriend Tara was in Nepal when the earthquake struck. Search and rescue expert James Perry is also here to tell us more about the search for survivors.
