Black Eyes Peas singer Fergie was reportedly banned from flying from Los Angeles to the UK on Sunday because she was deemed too drunk to fly.

An onlooker at the Virgin Atlantic gate told the Mirror: “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.”

A spokesperson for the airline confirmed that “a female passenger was denied boarding as she appeared intoxicated and therefore unsuitable for travel” and the flight was delayed for an hour while her luggage was removed from the plane.

Fergie refused to comment about Sunday’s incident when she finally arrived at Heathrow on Tuesday.
