To be totally truthful, the wife and I were catching up on some tivo, when we paused, and went to live t.v., I wasn't really paying much attention until my wife said, "Is that Jennifer Lopez's nipple?"

Not sure if it really is her "nipple"... but it looks like some of it was trying to get out, as she and Cameron Diaz were sharing their, um, talents, at the 2012 Oscars...
