GLITZ

Everyone’s favorite German animal trainers and magickers, Siegfried and Roy, are heatedly preparing for their upcoming world tour and walkabout. But the pair did take pause Monday to become bona-fide U.S. citizens in (where else?) Las Vegas. The duo’s longtime producer, Kenneth Feld, witnessed the swearing-in, along with other close friends. Cast members from the pair’s world-touring show, “Beyond Belief,” joined the two new Americans at an “all-American” party Tuesday overlooking the Cashman Field baseball diamond at the University of Nevada at Las Vegas. The menu? Hot dogs and apple pie.
