A racy performance on Dancing With the Stars in Argentina turned shocking -- even by South American standards -- when contestant Cinthia Fernandez took it all off for TV viewers and a studio audience, which included her parents.

By the time she got completely naked, Fernandez had already raised eyebrows by removing her skimpy bikini top to reveal gold-painted breasts.

When Fernandez took it all off, the host covered a camera with his hand. But there were other cameras, and at least one of them caught it all. Click here to watch the naked performance via Gawker. (YouTube has sinced removed a video due to its explicit nudity).

Fernandez tweeted an apology for the incident.
