Former WWE superstar Chyna collapsed in front of the main stage at a XXX convention in Miami moments ago … TMZ has learned.
Sources at the scene tell us … Chyna was hanging out at the 2012 Exxxotica Expo when she suddenly dropped to floor.
We're told several people rushed over to help … and carried Chyna out of the expo and into a nearby hotel where she's now resting.
Sources say Chyna was checked out by paramedics at the scene — who didn't feel the porn star needed to be hospitalized.
