WILL Simon Rex (a k a “Dirt Nasty”) go the route of Chris “Ludacris“ Bridges? Bridges went from rapper to acclaimed actor after starring in “Crash” in 2004, and now Rex has “landed a serious role” in the film “King of the Avenue,” a source said. In the flick, which also stars Esai Morales, Rex plays the adopted drug-dealing son of Ving Rhames. We’re told the whole crew is now filming in Puerto Rico.
