If Tom Selleck is Las Vegas' "new James Caan," then who is being called upon to fill Nikki Cox's... (hmm, I best not complete that thought). TVGuide.com has learned that Camille Guaty, familiar to TV fans from her runs on Prison Break (as Maricruz No. 1) and The Nine, is joining the NBC drama this season as Piper Nielsen, a "feisty new casino host." Hey, as long as they save some "feist" for Sam, I'm down with that.
