She is "starring" in The Avengers XXX: A Porn Parody. At least they gave her the right part, she's portraying She-Hulk (which unfortunately ruins one of my favorite comics characters FOREVER, but whatever). For those not familiar, She-Hulk is exactly what it sounds like: a female Hulk-actually the Hulk's cousin or something, given his powers via blood transfusion. So think "green chick Captain Kirk boned", with far more muscles (dammit, there goes another fantasy!) She-Hulk also has a history of being kind of easy to bed down, so it won't be much of a stretch for Chyna.
Sorry if I ruined anyone's day, but the news must be told.
