Wowser! Talk about a big gig! Miranda Lambert and Blake Shelton will sing "America the Beautiful" during the pre-game ceremonies this Sunday at the Super Bowl, and Kelly Clarkson will perform the National Anthem.  I can only imagine how nervous they must be, with an estimated worldwide audience in the billions. Even if you can sing the song in your sleep, it's a good bet you're worried about stumbling on the biggest stage in the world. ( Just ask Christina Aguilera)

The world will be watching, and so will we...good luck Blake and Miranda!
