from www.tmz.com – Former WWE superstar Chyna is finally getting back in the ring … taking on 9 dudes at the same time … except it’s for a porno movie.

TMZ has learned … Chyna was totally serious about pursuing a XXX career … and just wrapped up on a Royal Rumble-inspired flick in which she locks up with a bunch of dudes who all look like famous wrestlers … including a wannabe Hulk Hogan, wannabe Triple H, wannabe Ric Flair and more.

Weird thing is … Chyna and the REAL Triple H actually dated for a while before he married Stephanie McMahon back in 2003.

The WWE obviously has no affiliation with the Vivid Entertainment flick. We called the wrestling titans for comment, but haven’t heard back yet.
