Black Eyed Peas singer; Fergie, 31, was banned from boarding a jet for being drunk, reports Mirror.
The singer was set to fly from Los Angeles to Britain with bandmates when airline staff saw she was slurring her words and could hardly stand.
Fergie, who has battled drink and drugs, drunkenly raged at them and had to be pulled away by friends.
One witness said: "She was falling all over the place and had to be supported. She was in no state to fly."
"But when she was prevented from boarding she couldn't believe it.She was drunkenly ranting at staff but could barely string a sentence together. It was very embarrassing."
The flight was delayed for an hour as her luggage was removed. Fellow Black Eyed Peas stars Will.i.am, Apl.de.ap and Taboo remained on board but two aides stayed behind with Fergie.
