It was the nip slip
heard seen 'round the world! At the Super Bowl halftime show in in 2004 (ten years ago!), Janet Jackson's nearly-bare breast spurred a whole lot of controversy.
Here's what happened: While Janet was dancing with Justin Timberlake during his performance of "Rock Your Body," JT ripped off a part of her bustier, exposing her right boob and a sun-shaped "nipple shield." Because they're both pros, after Janet covered up, the show went on without further incident... at least until they got off the stage.
Even after Janet and Justin both apologized — the latter coining the term "wardrobe malfunction" in the process — Janet's boob's half-second of fame ended up embroiled in an eight-year legal battle with the FCC and the Supreme Court. After a heated, national debate on decency standards, Superbowl network CBS ultimately lost, and was fined $550,000.
