Preparations for Super Bowl In Full Swing

INSIDE EDITION goes behind the scenes as preparations take place for Sunday's big game between the New York Giants and New England Patriots.

On Thursday, Madonna appeared at a packed news conference to talk about her halftime show on Sunday and showed off some of her dance moves.

She will perform five songs during the ten minute halftime show, which will be viewed worldwide by the biggest TV audience of the year. 

Is she actually nervous?  

"I have never freaked out as much as I have or maintain my sanity to try and make the most amazing show for the Super Bowl," Madonna said at the press conferance.

Meanwhile, Supermodel Gisele Bundchen is making a heavenly plea on behalf of her husband, New England Patriots quarterback Tom Brady, as he leads his team against the New York Giants.

Bundchen sent this stunning e-mail addressed to friends and family saying:

"I feel Tommy really needs our prayer, our support and love at this time. So I kindly ask all of you to join me on this positive chain and pray for him, so he can feel confident, healthy and strong. Envision him happy and fulfilled experiencing with his team a victory this sunday.
Love, G :)"

The e-mail was obtained by the Giants hometown newspaper, The New York Post, which responded: "Not A Prayer."

When Madonna was asked at the press conference what she thought of Bunchens e-mail, Madonna responded, "She is a good wife."

As thousands of fans stream into Indianapolis ahead of the big game, INSIDE EDITION's Megan Alexander got a look at the tight security that's in place around Lucas Oil Stadium. 

Every single vehicle needs to go through a checkpoint

Over 600 trucks a day will go through extensive X-ray screening before they get anywhere near the stadium. X-ray machines are attached to cranes that allow the entire truck to be scanned top to bottom.  

Brian Bell, U.S. Customs Border Protection told Alexander, "We're able to see right through the vehicle, we can detect any type of explosives, weapons, people any type of anomalies."

Bomb-sniffing dogs are also on high alert.  

INSIDE EDITION got a demonstration. ATF agents hid a trace of an explosive on a car and this kind of dog is trained to sit if it smells a possible bomb.  

Thousands of fans have tickets for the big game but thousands more are packing Super Bowl village, set up outside the stadium.  

The hottest attraction for Super Bowl fans is a zip line that's 14 stories above street level.

Alexander said, "This is the first time something like this has been at the Super Bowl, and people are loving this. A thousand people a day are doing this ride."

Alexander had the guts to do a ride for our camera's. She was nervous, but was harnessed up and made the jump. She dipped an astonishing 800 feet above the crowd.

Alexander says the experiance was, "So scary, but so fun!"
