PWInsider is reporting that Rey Mysterio was backstage at WrestleMania last night.
There was speculation in the past few weeks that the former World Champion would make an unannounced cameo on Mania but that did not occur.
Mysterio last appeared in a WWE ring at Royal Rumble in January, which garnered millions views on YouTube after the event.
