For as media savvy as starlets have gotten over the past decade, accidents still happen, and Katy Perry is living proof, as she just showed the world her nipple in a see-through black dress! Camera flashes have a way of exposing what's underneath a woman's clothing, which is why many celebs - including Perry in this pic - opt for privacy patches. While we do detect a nipple patch here, it's no match for Perry's famous breasts, which proudly shine through!

This look will go down in infamy for a number of reasons. In addition to giving us our weekly tit fix, Katy wore this during her appearance Jimmy Kimmel Live!, where she shocked fans by announcing her retirement from American Idol after a seven-season run.

Perry is far from the first celebrity to show us her boobs in a see-through outfit. Check out our playlist for the best see-through nude scenes in movies and television!
