The two-time Grammy winner Ed Sheeran made a royal faux pas while receiving the Member of the Most Excellent Order of the British Empire (MBE) honour from Prince Charles at Buckingham Palace. Sheeran touched Prince Charles' arm while receiving the honor during a Buckingham Palace investiture ceremony. The picture that is doing rounds on the social media shows the 26-year-old singer touching Charles' arm as he shakes the royal's hand. The move has raised eyebrows as Royal etiquette dictates that touching shouldn't go beyond a handshake. The ‘Shape of You singer' was bestowed the MBE honour for his glittering musical career and charity work.
