Scottish singing sensation Susan Boyle stunned passengers in a VIP lounge at the Heathrow airport as she flew off the handle, grabbed a mop and started singing and dancing around.
The 48-year-old singer suddenly grabbed the makeshift "microphone" from a cleaner as she suffered another public meltdown, The Sun reported online.
During her bizarre performance, which sparked complaints to British Airways staff, she also polished passengers' shoes.
The Airline employees tried to calm her down only for Boyle to flee the Terminal 5 lounge, yelling, "I've escaped, I've escaped!"
"It was chaos. Susan was very restless and agitated from the minute she walked in and immediately started making a scene. She was singing and dancing around, shouting obscenities at full volume," a source said.
The 'Britain's Got Talent' star's wild spree was finally ended by an official who sat with her until she boarded her flight to Chicago to be a guest on the Oprah Winfrey show.
"A customer in the BA lounge on Tuesday was asked to temper their behaviour as it was becoming disruptive," a spokesperson for British Airways said.
