Miley Cyrus had another nip slip in 2013. The "Wrecking Ball" singer's cleavage made an unexpected appearance at this year's iHeartRadio concert after her split with Liam Hemsworth.

According to E! Online, the controversial singer, 20, was bound to have a wardrobe malfunction after several months of wearing provocative outfits.

While onstage at the Las Vegas concert on Saturday, Cyrus exposed her cleavage unintentionally. The former Disney darling was dressed in a white lace-up corset and short shorts during the set including songs, "We Can't Stop" and "Wrecking Ball."

Cyrus didn't notice her nip slip and was very much into performing. At one point, the singer cried while singing "Wrecking Ball," E! reported.

And though her onstage outfit was very racy, her off-stage ensemble was even more jaw dropping. The pixie-cut blonde had on a white mesh dress with fur sleeves over black pasties when she performed a second set at the MGM Grand Garden Arena on Saturday night.

And many of the iHeartRadio attendees and other performers supported Cyrus.

"She does what she wants," said The Wanted's Jay McGuinness to E! News. "I think her wardrobe is kind of interesting, but hey, we're in our twenties, so I'm like, 'Yeah!'"

"The Vampire Diaries" star, Kat Graham loves Cyrus' style, too.

"I'm a huge fan of her fashion sense," Graham said. "I think she is winning, so I have nothing [bad] to say. So, I guess keep doing what you're doing!"
