I think it was premeditated too, especially because even if it was really planned that Justin would rip it off and only red lingerie would be shown - let's "guess" that the lingerie got out of place when he did the movement, and so the boob was revealed - but wait, so she normally just walks around with a sun around her nipple?!
Yes, I believe it was a stunt. But still, it's only a boob, it's nothing outrageous or indecent.
I've also heard on the news like 5 minutes ago that they're gonna broadcast a delayed version of the Grammys (CBS), and also of the Oscars (ABC) so they can 'fix' last minute 'inconvenients' as any kind of 'sexual publicity stunts' or 'controversial political messages'...
No comment.
