Emma Watson revealed a little more than side-boob in a slinky Giorgio Armani dress at the Los Angeles premiere of The Perks of Being a Wallflower on Tuesday. Fortunately, the 22-year-old Harry Potter actress was wearing pasties—those handy-dandy plastic nipple cover-ups—and thus did not expose her whole nipple to the paparazzi. But they still managed to zoom in on a bit of pink flesh and captured Watson’s bashful smile in the milliseconds after the incident occurred.

Where were you when J.Lo had a wardrobe malfunction? Jennifer Lopez wore a stunning Zuhair Murad gown, but—sadly for her—the night will forever be remembered for one slip of her top. When presenting with Cameron Diaz, the American Idol host's dress may have shifted enough to expose her nipple. The Internet immediately was set on fire, searching for the truth. It even spawned this Twitter account. Will we ever know the truth?

Lawyer, journalist, and victim of a wardrobe malfunction? Nancy Grace performed a revealing quickstep on Dancing With the Stars Monday. The HLN host’s dress failed her mid-performance, exposing her nipple. While ABC cut away to the audience, Grace was consoled by her partner. Host Tom Bergeron acknowledged the blooper by joking that the malfunction was fine for the European version of the show. "It was a bit top-heavy at times, my darling. And I got an eyeful!” said judge Bruo Tonioli of Grace’s dance. Watch the video here.

That’ll wake people up—ABC’s Good Morning America gave East Coast viewers a full flash of hip-hop star Nicki Minaj’s breast on Friday. The diva, who emerged on the public scene with help from rapper Lil Wayne, has quickly gained popularity, as much for her colorful approach to fashion as her lyrical style. Her first embarrassing wardrobe moment was aired live on morning television and triggered a blistering attack from the Parents Television Council, which said GMA’s programmers “need to stop apologizing and implement the five-second delay that so many Americans have been calling for.”

New Jersey club-goers got more than they bargained for over the weekend, when Kelly Rowland flashed them from the stage. The soon-to-be judge on The X Factor in Britain failed to notice that her bustier top had let her down, leaving both of her breasts exposed to the camera-happy crowd. Rowland, 30, laughed off the double nip-slip, using Twitter to address the controversy: “New Jersey crowd was amazing!! hope you enjoyed the show and didnt mind the peekaboo LOL!!! #kanyeshrug #stuffhappens.”

Who could have guessed that a football game would become the scene of the most notorious wardrobe malfunction of all time? Near the end of singer Janet Jackson’s high-energy performance at Super Bowl XXXVIII’s 2004 halftime show, singing partner Justin Timberlake ripped off half her top, exposing her right breast for less than a second. “Nipplegate” rocked the country: Although Jackson was wearing nipple jewelry, almost 8.9 million viewers were given a show, and the Federal Communications Commission had a field day. The “wardrobe malfunction” incurred a half-million dollar fine from the FCC, which then, thanks to Jackson, set unprecedented standards for indecency violations.

Lady Gaga has gained notoriety and fame by working avant-garde fashion looks on the red carpet, but this time, the controversy had nothing to do with meat. Attending this year’s CDFA Awards to accept the Fashion Icon award, the gay-rights advocate let it all hang out, inadvertently showing both breasts while posing for photographers. Gaga didn’t let the exposure bring her down—for the after-party, she simply affixed black electrical tape to her nipples and rocked the sheer bodysuit.

Better known for her figure than her acting chops, former Baywatch star Pamela Anderson inadvertently gave the Paris audience at Vivienne Westwood’s ready-to-wear collection a peep show in early 2009. While working the runway, the busty blonde showed off her assets twice—first in a casual tank-top look, and then again while escorting the designer down the runway.

Romantic comedy queen Katherine Heigl was mid-acceptance speech during her ill-timed wardrobe malfunction at the ShoWest awards in 2010. While taking home a trophy for Female Star of the Year, the Mormon beauty noticed her elegant red gown’s broken strap just in time to avoid flashing the crowd. Host Billy Bush offered Heigl a helping hand to keep her dress in place, addressing the incident in a later tweet: “I fought some adolescent instincts.”

Certainly no stranger to the caught-on-camera nipple slip, former O.C. star Mischa Barton made quite a splash at London Fashion Week in 2008. After sitting front row at the Fashion for Relief fashion show at the Natural History Museum, Barton gave photogs a glimpse of her bare left breast upon exiting a taxi. Not to out-do herself, the actress has had similar slips on both sides in the years since.

If you’ve been following recent headlines, it’s hard to believe that Voice judge Christina Aguilera was once the untouchable queen of pop music. With her massive hit “Beautiful,” the star’s power-packed, soulful voice helped her win a Grammy for Best Female Pop Vocal in 2004. Accepting the award without baring all was a challenge for Aguilera, who referred to Janet Jackson’s “Nipplegate” while adjusting her satin gown onstage. Rumor has it that upon returning to her seat, the singer wasn’t so lucky.

The 81st Academy Awards were full of surprises and celebrity sightings, but none got more attention than the star-packed opening number: a family-friendly tribute to all things musical. Actor Hugh Jackman gave singer Beyonce a dramatic dip center-stage that left little to the imagination, and her sassy red outfit slipped down for a wardrobe malfunction barely noticeable to viewers at home. Internet gossip rags, however, wasted no time producing a screen shot.

Tara Reid hasn’t been able to catch a break since her American Pie glory days—from botched plastic surgeries to heavily scrutinized hard partying, the actress also takes the crown for most infamous nipple slip of all time. The red carpet for Diddy’s 35th birthday party was all glamour and glitz until Reid faced photographers, her black dress slipping past her breast for a painful near-minute-long exposé. The actress’ publicist eventually helped her cover up, well after the media had captured the damage.
