Drudge has some closeup pictures on his site. Janet was wearing something more exotic than a pasty, it was some sort of weird fiery sun shaped piece of jewlery that appears to clip around her nipple. I can't imagine she would normally be wearing this sort of thing to a performance unless she fully intended to display it.
CBS is the same network that bailed out of showing "The Reagans" recently because it was supposed to be offensive to right-wing conservative types. Now they show a bare breast to their same audience. Lol, they deserve the grief they're getting. These network execs are such idiots. Yes, I understand it is publicity for the network, but to what end?
Anyway, I've noticed that American network (I mean CBS, NBC, ABC, Fox, A&E) has gotten more and more daring over the past few years. Many times I've caught shots of naked breasts on these networks, but always from the side or from below the nipple (e.g., ST: Enterprise has done this), and always with the nipple discreetly covered by a finger or two.
Well, it's only a matter of time until you have full frontal nudity in the States on regular network tv, just like we have in Canada and in much of the rest of the civilised world

Good or bad, I think it's inevitable.
