Chyna Gets Down and Dirty with Porn Star

Tara Reid has some competition for her crown as Hollywood's biggest train wreck -- Chyna Doll. The former WWE and "Surreal Life" star (yes, we're using that term loosely) was out partying with porn star Mary Carey ... and what a sight they were.

The two busty women were dressed in matching (and ridiculous) outfits, flirting with everyone they could, including each other, on their way out of Hollywood hot spot Shag. At one point Mary even grinds against Chyna, lifting the wrestler's skirt to an even more inappropriate length.

For Chyna though, the real fun started once they got in the car where she was spotted making out with an unknown male (poor thing), straddling him in the back seat as they drove off.
