Bet the over.

Las Vegas insider and Fox Sports radio host RJ Bell tweeted Sunday afternoon that a cameraman he knows said the Super Bowl LIII national anthem rehearsals were running between 1 minute and 59 seconds and 2 minutes. Most betting sites have the over/under at 1 minutes and 50 seconds.

Gladys Knight would go on to sing the anthem in 2 minutes and 1 second.

The length of the anthem has become a popular Super Bowl prop bet.
