Susan Boyle stunned passengers at London's Heathrow airport in United Kingdom with a string of bizarre actions, Bang Showbiz is reporting. The 'I Dreamed a Dream' singer was asked to calm down by officials in the VIP lounge after grabbing a mop from a cleaner, which she then used as a makeshift microphone before trying to polish fellow guests' shoes.

The report adds that when airline officials intervened, Susan Boyle fled the room shouting: "I've escaped, I've escaped." An unnamed source told The Sun newspaper: "It was chaos. Susan was very restless and agitated from the minute she walked in and immediately started making a scene. The source added that Susan Boyle is spotted singing and shouting around the airport - at full volume. Susan Boyle was flying to the USA to be a guest on Oprah Winfrey's talk show.
