You gotta love how CBS touted their "must see" half time show all week, and now they claim they had no idea that Janet Jackson's boob was the mystery guest.

UPDATE: It looks like I'm not the only Doubting Thomas. Drudge (link has photo*) claims that the CBS brass knew all along about the breast baring stunt. (not that there's anything wrong with bare breasts.)

Top CBS executives approved a musical skit where Janet Jackson would expose her breast during the MTV-produced Super Bowl half-time concert, the DRUDGE REPORT has learned.

"The decision to go forward went to the very top of the network," a well-placed source explained from New York.

The groundbreaking scene came during the most-watched television broadcast of the year -- and during the dinner hour for the nation's west coast viewers.
