DETROIT– Will Donald Trump put his hair where his mouth is?

Trump and World Wrestling Entertainment owner Vince McMahon will pick a wrestler to represent them in the ring April 1 at Wrestlemania 23 at Detroit’s Ford Field, The Detroit News reported last week.

If their pick is beaten in the “Battle of the Billionaires,” the loser will get his head shaved after the match, the Detroit Free Press reported Monday.

WWE spokesman Gary Davis said the date of the event had prompted speculation that it was a hoax. But it’s not an April Fool’s Day joke, he said.

“If Trump loses, he shaves his head,” he said.

The announcement of the match was made on a WWE television program that aired over the weekend.
