Miley Cyrus Wears Nipple Covers At US Festival

Miley Cyrushas taken to the stage at a US music festival wearing just a fishnet dress, skimpy panties and nipple covers.

The controversial pop star had earlier worn a two-piece bra and corset ensemble for her set at the iHeartRadio event in Las Vegas - during which she appeared to get emotional and shed a tear at one point.

The site also reports: "Before the former Hannah Montana star's breakdown, she hit the stage in a white barely there crop top and hot pants combo, dancing around and twerking for the crowd."

The event was the 20-year-old singer's first public performance since her split from Liam Hemsworth was made public last week.
