The 'Only Fools and Horses' star's boy was best known for portraying Ollie Coulton on CBBC's 'So Awkward', and his friend Samuel Small has paid tribute to his pal, admitting the late actor was "so full of life and had touched so many people's hearts".

'Game of Thrones' star Samuel wrote on Instagram: "To my brother Archie. I still can't quite comprehend that you have passed. You still had so much life to live and I'd give anything for you to keep on living it. My heart aches all day and everyday thinking about you and I just wish I could talk to you just one more time so you could know how much I loved you. I vow to make you proud with every last breath. Love you from now until infinity. Rest in power bro.

"I wish you could've all known Archie how we knew him. I've never met someone so full of life and had touched so many peoples hearts. Archie was there for me in my lowest lows but my highest highs were with him. Archie's my best friend and to say goodbye so soon is absolutely devastating, but his calling was obviously somewhere else and I hope he is brightening up wherever he is. To be honest, I still can't find the words that do him justice and show how much of a beautiful soul he was, but his mission was to make as many people happy as he could and trust me, he really really did. Archie loved his friends and family so so dearly and we hope he knows how much he truly was loved. We never know what tomorrow will bring so hug the ones you love extra tight as Archie always did (sic)"

Archie's mum Lucy Lyndhurst commented: "He will love you and watch over you forever. love you dearly."

According to The Sun Online, Archive was found at his family home in Fulham last week in non-suspicious circumstances.

Police are no longer said to be actively investigating, and an inquest into his death is to be opened next week.

Archie also starred as a young version of Jack Whitehall's 'Bad Education' character Alfie Wickers in the sitcom in 2014.
