Halftime Show Exposure, Accidental Shocker or Staged?

Timberlake blamed a "wardrobe malfunction," but Federal Communications Commission chief Michael Powell called it "a classless, crass and deplorable stunt."

WASHINGTON — Some Super Bowl viewers think that flash of Janet Jackson's breast was inappropriate. Others liked what they saw.

But many agree it was probably a publicity stunt.

Jackson and Justin Timberlake were singing Timberlake's hit song

"Rock Your Body" during the halftime show. At the end, he reached across Jackson's leather outfit and tore off the covering to her right breast.

Timberlake says in a statement that it was not intentional.

A few are giving the two performers the benefit of the doubt. One woman says part of the performance could have gone wrong.

But one man says he thinks Jackson gets "a kick out of" stripping in front of people.

Meanwhile, Michael Powell -- head of the Federal Communications Commission -- says the musical number that ended with singer Janet Jackson's breast exposed was a "classless, crass and deplorable stunt."

Powell says he's "outraged" by it. He says he and his family gathered around the TV to see a "celebration" -- but that it was "tainted" by the exposure of Jackson's breast. He says he's told the commission to launch an investigation.

Singer Justin Timberlake, who was performing with Jackson and who ripped away part of her costume, calls it a "wardrobe malfunction."

CBS and MTV -- which produced the show -- each say they had no idea it would happen. CBS says it "deeply regrets the incident."
