She’s not exactly known for her demure style and conservative fashion choices.

But Miley Cyrus showed off more more than she bargained for at Saturday’s pre-Grammy bash in LA when she nearly popped out of her daring black gown.

Displaying a hint of sideboob throughout the evening, the actress nearly came a cropper when the risqué dress gaped open to reveal a clear nipple cover.

Living up to her wild child reputation, the 20-year-old left little to the imagination in the floor-length, black Emilio Pucci halter-gown and was constantly checking that it preserved her modesty.

Looking typically edgy with her blonde hair spiked up and showing off a hint of leg under the sheer dress, the star spent the evening mingling with friends at the bash honoring L.A. Reid at the Beverly Hilton.

Adding to her rocky look, the former child star wore black, smokey make-up on her eyes, Versace boots and jewelry from Lorraine Schwartz and Ofira.

Her long, black dress, which barely covered her chest was cut so that the singer’s dream catcher tattoo was clearly visible under her right arm.

The Hannah Montana star, who struck her tongue out in a number of snaps, spent much of the evening chatting to more demurely-dressed Katy Perry.

The raven-haired 28-year-old looked like a silver-screen angel in a Rafael Cennamo long-sleeve boatneck gown with pearl embroidery.

Not seen Saturday was Miley’s fiancé Liam Hemsworth, who will star in The Hunger Games: Catching Fire due out November 22.

The Hannah Montana star is currently working on her fourth studio alum, slated for a 2013 release.

Waiting close by was Perry’s on/off boyfriend since June, John Mayer.

But the California Gurls hitmaker has decided to make the Grammys a ‘Girls’ night this Sunday and she’ll be taking actress Allison Williams as her date.

‘I am going to the Grammys and Katy Perry is my date,’ the HBO starlet told Anderson Cooper Thursday.

Katy hung out with Allison at President Obama’s inauguration, and the gal pals reportedly got to know each other through John.

According to E! News, the lovebirds have even double dated with the Girls actress and her boyfriend, College Humor founder Ricky Van Veen.

John has a notorious reputation for loving and leaving some of Hollywood’s most eligible ladies, including Taylor Swift, Jessica Simpson, Jennifer Aniston, Jennifer Love-Hewitt, and Minka Kelly.

‘I was just a jerk,’ the Born and Raised singer admitted in a sit-down interview with CBS Sunday Morning airing February 10.
