CHYNA COLLAPSES At Porn Convention

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.

We reached out to Chyna — so far, no word back … but we do know she’s canceled a Friday afternoon appearance at the XBiz Summit — another porn convention.
