Fergie

Notorious pisser and first lady of the Black Eyed Peas, Fergie drank a few too many before a flight to the UK in '07. During the boarding process, a fight ensued as the crew tried to inform the Duchess that she was too twisted to be on an airplane. Being twisted, she did not want to hear this. Tabloids caught the rant, describing how Fergie's friends (read: Will.i.am.) held her back. There's no mention of her peeing her pants during this altercation, but given her history, we'll count her guilty until proven innocent.
