The scene of the crime this time is an airport. A VIP lounge in Heathrow, no less.

Sources report that Susan took a fancy to a cleaner's mop and began crowing into it like the "makeshift microphone... During her bizarre performance - which sparked complaints to British Airways staff - she also used it (the mop) to polish passengers' shoes. Airline employees tried to calm her down only for SuBo to flee the Terminal 5 lounge, yelling: 'I've escaped, I've escaped!'" Sorry, that's funny. And it sounds like she was enjoying herself, which is the main thing.

A witness speaking to The Sun said: "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."

It took a B.A. official to calm her down, by way of sitting with (or possibly on) her "until she boarded her flight to Chicago" - as she's due to appear on the Oprah Winfrey Show (let's hope she's reinforced the couches). The airline later confirmed that "a customer in the BA lounge on Tuesday was asked to temper their behaviour as it was becoming disruptive."

That doesn't sound like a complete meltdown; she was just being a little bit Rock 'n Roll is all. If she'd been swinging out of a mop outside the Boots in the departures lounge singing her heart out, instead of a w*nky VIP lounge, she would've got a rapturous round of applause. And another YouTube hit.
