Katherine Jenkins OBE has revealed the sweet moment the Queen saved her from a potentially embarrassing moment early on in her career.The Welsh singer, 41, explained she was invited to Buckingham Palace in her mid twenties for an "intimate affair". Katherine was among just six guests and, being an outsider to royal tradition, she was nearly left red faced when she was presented with a glass bowl of water and the offer of fruit. May sound silly, but if you were sat besides royalty there's no way you would want to put a foot wrong.
