Fergie has a wardrobe malfunction...

She may have sold millions of records and have assistants to ensure she looks flawless, but The Black Eyed Peas singer Stacy "Fergie" Ferguson can still have a wardrobe malfunction.

The 23-year-old suffered a slight wardrobe malfunction when she opened for The Police at Wellington's Westpac Stadium.

Fergie danced and sang a selection of her hits, embarrassingly unaware the zip was down in her tight white trousers.

Teamed with a white waistcoat, Fergie showed off her toned physique and would have looked her usual groomed self if it wasn't for the noticeable trouser disaster.

The stadium was jam-packed as around 22,000 fans flocked to watch The Police kicking off their Australasian tour.

The Police comprise front man Sting, drummer Stewart Copeland and guitarist Andy Summers.
