On the heels of the "Battle of the Billionaires" signing at "Monday Night RAW®" when tempers flared as business icon Donald Trump shoved WWE Chairman Vince McMahon to the canvas, the two, along with an exciting roster of WWE's most revered Superstars, will hold a press conference announcing plans for WrestleMania® 23, to take place LIVE on Sunday, April 1 at 4pm PT / 7pm ET. Stone Cold Steve Austin™ will police the "Battle of the Billionaires" as the special guest referee between Donald Trump's designated wrestler, ECW® World Champion Bobby Lashley™ and Vince McMahon's designated wrestler, "The Samoan Bulldozer" Umaga™. If Lashley wins, Trump will shave off McMahon's hair, but if McMahon's wrestler wins, Trump will have his hair shaved off live in front of a worldwide pay-per-view audience and more than 75,000 cheering fans at Ford Field in Detroit.
