This little boy dressed as a Queen's Guard will melt your heart!

Four-year-old Marshall Scott had his birthday made perfect after a Guardsman posed with him for photos after spotting the little boy dressed up in a miniature guardsman uniform.

Marshall's mum Imogen had taken him for a visit at Windsor Castle and they watched the Coldstream Guardsman march into the building. Shortly after, one of the Guardsman returned to meet the little boy. The adorable video has quickly gone viral, and his mum Imogen Scott spoke to HELLO! Online about the brilliant moment. "I am still in shock from it all," she said, speaking about the video's popularity. "I just wanted to share was his fantastic day with friends and family and then I just saw the video and pictures pop up everywhere I couldn't believe it." According to Imogen, Marshall is a huge fan of the royal family, and would love to be a member of the Queen's Guard himself when he's older. She said: "He's is so patriotic! He sits and watches documentaries about the Queen and family. He definitely wants to be a Queens Guard when he's older."
