Behind the Scenes of Super Bowl XLVII

ET was in New Orleans at the Super Bowl on Sunday to capture all the behind-the-scenes action at the biggest annual event in American sports. From the pre-game performances to the talked-about power outage, Rocsi and Rob Marciano caught up with celebs and fans as the Baltimore Ravens and San Francisco 49ers battled for the Lombardi Trophy.

The Super Bowl has grown well beyond just a game between two football teams and is now engraved into American culture. As fans frantically flocked to The Big Easy for the game, celebrities were just as excited to be there in the tremendous atmosphere.

"We've been running around all day saying, 'Happy Super Bowl Day' to everybody," said Matchbox Twenty vocalist Rob Thomas, who performed with his band before the game. "...As soon as we got here, there was this [feeling] like, 'It's not just any day; it's Super Bowl Day.'"

OneRepublic front man Ryan Tedder revealed that he and his band mates, who also preformed in the pre-game concert, were thoroughly enjoying New Orleans and its fried cuisine.

While the bands were split between which team they were rooting for in the game, Katherine McPhee tipped the balance towards her home-state 49ers. After an encounter with San Francisco's head coach Jim Harbaugh's son, the Smash star landed herself on the sidelines.

Also on the sidelines amongst a group of photographers was former NFL running back Ricky Williams, who played with the Ravens last season before ending his football career.

Nearly as hyped as the game itself was Beyonce's halftime performance, which featured a reunion of Destiny's Child as had been rumored. As electric as the halftime show was, it was overshadowed by a power outage in the Superdome that occurred a few minutes into the second half.

While half of the power in the arena was restored by back-up generators, it took over half an hour to resume the game, which gave Rocsi and Rob an opportunity to investigate and gauge celebrities' and fans' reactions to the outage.

"It was very surreal because you can't imagine that [the power] would go out and stay out that long," said actress Holly Robinson Peete, who is married to former NFL quarterback Rodney Peete. "My biggest concern was for the athletes because the momentum [was on] one side. That's just the worst feeling ever."

While it's uncertain if the blackout played a role, the 49ers surged back in third quarter to narrow the deficit to five points, which made the game exciting until the finish. However, when the final whistle blew, the Ravens led 34-31 and were crowned Super Bowl XLVII Champions.
