WWE legend Rey Mysterio had a music superstar help him defeat his own son, Dominik, during WrestleMania 39 on Saturday ... with Bad Bunny playing a pivotal part in his win.
The whole match was set to be a star-studded event from the beginning ... with Snoop Dogg helping Rey make his grand entrance at SoFi Stadium.
When the bell rang, it was a hard fought matchup between father and son ... but one thing that wasn't on Dominik's side was the superstar artist -- the former WWE 24/7 Champion, who patiently awaited his opportunity to help Rey out.
