SAM Thompson has been given a huge boost during his 260-mile endurance challenge after being surprised by a massive A-lister. The telly and radio star, 34, was left screaming with amazement after receiving some words of encouragement from the Hollywood actor. Sam had called in for a pitstop on Thursday morning to chat to Colson Smith live on This Morning. But before continuing on his way, Sam - who has torn his calf muscle - was given the ultimate lift. Orlando Bloom spoke to the former Made In Chelsea star live from the This Morning studio - and Sam was gobsmacked. Realising who was speaking to him, Sam began yelling and attempting to jump up and down with his painful legs. He then listened open-mouthed as Orlando gave him some encouraging words as he nears the end of his gruelling Unicef challenge for Soccer Aid. The British actor, who has starred in blockbuster movies Lord Of The Rings and Pirates Of The Caribbean, told Sam: "We are so proud of you, mate! "It's amazing what you are doing. You're in the home stretch, we're all pulling for you. "Like you, I have seen the work Unicef do in the field, it's amazing. "You're a hero, everyone donating is a hero. I'm going to throw some at you as well. I hope it helps. "You are remarkable. I only wish I could find time to come out and see you and cheer you over the line. "But it's incredible what you're doing and Unicef, as an ambassador for many years, we are so grateful for all the women and children's lives around the world you're changing. "Congrats, mate. We're pulling for you." Sam screamed: "Oh my god, Orlando Bloom!" Orlando - who has been an ambassador for Unicef since 2009 - said the exchange "brought a tear to his eye". Sam is on the penultimate day of his five-day Match Ball Mission. He has been tasked with transporting the Soccer Aid ball 260-miles from Stamford Bridge in London to Old Trafford in Manchester. Sam is running and cycling the journey and aims to complete it on Friday June 6. On Wednesday, the former I'm A Celebrity...Get Me Out Of Here! star broke down in tears as he was surprised by Pete Wicks. In a heartwarming clip, Pete could be seen waiting for his best pal as he approached him on his run. Sam was seen limping due to his calf injury and, upon seeing his BFF, he burst into tears. Pete pulled him in for a hug and gave him a kiss on the cheek. “You all right? Come here. It’s alright,” Pete said to Sam. The tearful reality star replied: "I didn't know you were coming." Pete said: “Of course I'm coming, do you think I’d miss this? Come on, I’m so proud of you. Look how proud I am. You’re smashing it." Struggling to compose himself, Sam said that he didn’t think he was "smashing it". Sam is completing the challenge in support of Soccer Aid, which takes place on Sunday June 15.
