Controversial singer Miley Cyrus shocked her fans with a video of two men performing a nipple piercing on a prosthetic breast.

"Pierce dat b***h," Cyrus captioned the short clip showing one of the men holding the artificial breast while the other man uses a drill during the painful-looking procedure, reports aceshowbiz.com.

The whole thing is fake, of course, but it's enough to shock the 23-year-old's followers on the social media.

One fan who thought the video's a hint that the "Wrecking ball" hitmaker would really pierce her nipple wrote, "Don't do it, Miley. We love you just the way you are. You are beautiful."

Some other fans who had planned to pierce theirs said that they changed their minds.
