Janet Jackson's infamous wardrobe malfunction at 2004's Super Bowl has gone down in history -- the phrase has been entered into the English dictionary.

Jackson, who was performing during the Super Bowl's half-time show, was left red-faced after her stage partner Justin Timberlake ripped open her top, revealing a breast.

More than 90 million people saw the live broadcast, and the term "wardrobe malfunction" was coined.

It has now been entered into the latest Chambers English Dictionary.
