It's being billed as the Battle of the Billionaires -- Donald Trump vs. WWE mogul Vince McMahon.
The two are set to settle their brewing feud on "WWE Raw," with the loser being forced to shave his head. Unfortunately, The Donald himself won't be stepping into the ring to fight, with both McMahon and Trump sending in WWE fighters to do their dirty work for them.
Trump stripped of his infamous hair? Rosie O'Donnell might even tune in to see that! It all goes down tonight on USA, leading up to WrestleMania 23, airing April 1st on Pay Per View.
