During a performance, Justin Timberlake (formerly of NSync) tore off half of Janet Jackson's bra, revealing her breast.
The duo were dancing to her All for you track when the fiasco took place.
Apparently, the move was planned. Rumours say the broadcasters, CBS, had approved the rip-off, though MTV claimed to be 'unaware' of it. Janet and Justin later apologised for their stunt. America is still outraged.
