At this year's Super Bowl, people aren't just gambling on whether the Patriots or Seahawks will win. They're also cashing in on Katy Perry's cleavage. Yep, that's right. Folks over at BetOnline, a gambling website, are placing bets on whether or not the Super Bowl performer will bring her puppies out to play during this Sunday's game.

Based on Katy's past performances, it's no surprise that the odds (currently at -500) favor her showing off a lil' somethin' somethin'. In other words, betting $500 on "Yes, KP will show cleavage" will get you only $100 -- but betting $100 on "Nope, she'll cover up" will get you $350.

Somehow we don't think this is what Katy meant when she sang "shut up and put your money where your mouth is" in her song "Waking Up In Vegas."
