Last weekend's iHeartRadio Music Festival didn't skimp on the showstoppers.

There was plenty to grab your attention, from Miley Cyrus crying post twerk to Britney Spears' bra top and Justin Timberlake's new music debut.

But it was Aubrey O'Day's bootylicious getup that stole the spotlight. Don't let the demure side fool you.

The Danity Kane diva wore a black mullet-inspired ensemble -- business (as far as corsets and lace go) in the front, full-on party in the back, as one can see behind the scenes.

This "Bad Girl" is no stranger to displaying her body. Earlier this month, O' Day documented her weight loss goals in selfies and vacation bikini pics.

Keep at it, Aubrey! You are killing it.

  • Katy Perry

    Katy Perry showed up at the 55th Annual Grammy Awards on Feb. 10 with a boob window so wide, even <a href="http://www.huffingtonpost.com/2013/02/10/ellen-degeneres-katy-perry-grammys-2013_n_2659221.html">Ellen couldn't help but gawk</a>.

  • Kelly Rowland

    Kelly Rowland defied all logic when she showed up to the Grammys in a dress that had more slits than fabric, yet still managed to look <em>hottt</em> and avoid any nip slips (or worse!)

  • Jennifer Lopez

    Leave it to J.Lo to channel Angelina Jolie -- and one-up her. Lopez's high slit dress had us worried we might get an unwanted sneak peek at her hoo-ha, but the lady is clearly a pro and she pulled off walking around in that thing like it's nobody's business.

  • Rihanna

    RiRi's dress at the Grammys was supposedly on point with CBS' requests, but up close you could totally see her nipples. Accident? When Rihanna is involved, we think not.

  • Samantha Barks

    "Les Mis" actress Samantha Barks had a pretty inventive way of showing off her tatas at the Elle Style Awards Feb. 11, with this square-ish peek-a-boo window.

  • Ashley Greene

    The "Twilight" beauty attended the amfAR New York Gala on Feb. 6 showing an odd bit of skin that revealed much without revealing anything at all.

  • Alicia Keys

    Keys' Grammy performance with Maroon 5 was electrifying, but we couldn't help feeling uneasy during the show for fear her underboob would go into full "boob exposure" mode.

  • Alicia Keys

    The gorgeous lady is a repeat offender and even when she wasn't onstage, she walked the red carpet in a dress that was somewhere between elegant and S&M.

  • Alicia Keys

    Did we say repeat offender? Yeah, we meant it. At the 2012 MTV European Music Awards the singer bared her toned, beautacious bod in an unusual way.

  • Anja Rubik

    Remember when supermodel Anja Rubik put her hip bones on display at the 2012 Met Gala? Her obscenely high leg slit almost made us forget she's got one across her chest, too.

  • Zosia Mamet

    The breakout star of "Girls" was a guest on "Late Night With Jimmy Fallon" and made it quite difficult for the host to concentrate with her strategic slit.

  • Miley Cyrus

    Cyrus attended Clive Davis' Pre-Grammy Gala Feb. 9 and opted for a dress a bit too small on top... Unless she was going for massive sideboob, in which case, good going Miley!

  • Kim Kardashian

    The reality maven is not one to hide her growing baby bump or her moneymaking girls. Kim arrived at LAX Feb. 7 wearing a sheer blouse that left very little to the imagination.

  • Ashley Greene

    The actress is also a repeat offender, seen here baring her back during Fashion Week in New York City.

  • Ashley Greene

    Hmm... Not her best look yet? Greene went bandeau to the CFDA/Vogue Fashion Fund Awards and let her toned abs steal the spotlight.

  • Lady Gaga

    We expect nothing less from the Gaga, who showed up to the "Lady Gaga x Terry Richardson" book launch party wearing her underwear. Oh, and this thin, see-through lace bit, but who's even looking at that?

  • Gemma Cairney

    Another puzzling boob window at the Elle Style Awards, this time courtesy of Britain's Gemma Cairney.

  • Gemma Arterton

    Arterton presented at the BAFTAs on Feb. 10 and played a sort of guessing game with us -- is she, or isn't she showing?!

  • Melissa Benoist

    The "Glee" star attended the Golden Globes with a dress that would make the rest of us stand with our hands on our hips the whole night, for fear our love handles will come bursting through.

  • Kelly Osbourne

    Ditto the fashionista, who walked the red carpet at the Grammys in a cutouts clearly meant to show off her newly rocking physique.
