WWE just made a MAJOR change to WrestleMania 36 -- the event will be split into 2 nights ... and future pro football hall of famer Rob Gronkowski will be hosting the whole thing!!
Vince McMahon's org. just made the historic announcement Wednesday afternoon ... saying the ex-Pats superstar will be the face of the event from the WWE Performance Center in Florida.
The event is slated to go down April 4 and 5 -- in front of an empty crowd, thanks to the coronavirus pandemic.
As we previously reported, Gronk finalized a deal with WWE in a "part-time, cameo" type of setting last week .
