Sportsbooks split on how to handle Aguilera anthem

DALLAS, Texas -- Nevada's sports books posted hundreds of unusual and unique proposition wagers on Sunday's Super Bowl, won by the Green Bay Packers, 35-21 over the Pittsburgh Steelers.

One wager that wasn't posted was an over/under on how long it would take four-time Grammy Award winning singer Christina Aguilera to perform the National Anthem.

Nevada sports books didn't take the action because official statistics aren't kept on the song's length.

Online/offshore sports wagering website, however, took bets on the performance. According to covers.com, one online sports book placed Aguilera's rendition with an over/under of one-minute, 54.5-seconds.

However, the singer went out and botched the Star Spangled Banner by skipping one lyric and combining two others. Her re-mix may have thrown off the length of the performance.

According to replays on YouTube.com, Aguilera finished the song at 1:53.5, although some could argue she finished the song in 1:53.

"People expect singers to grandstand and drag the anthem out at big events such as the Super Bowl," Sports Interaction oddsmaker Greg Sindall told covers.com. "The over is always an overwhelmingly popular selection and that was the case."

Because of the controversy over the flubbed lyrics, covers.com said many online sports books voided the wagers all together. Others were split as some paid the over bets and others paid the under.
