I think it is pretty obvious what has happened to Pru. She has forsaken Texas to live a new life in Vegas as a showgirl. You know they have all those really BIG hat things, skimpy costumes, (I'm sure you all remember the Red Wiggler) high heels, adoring fans, etc.
And yes, I said showgirl, not exotic dancer. Of course she could pull that off (pun intended)if she wanted too, since she has those awsome boobs!
