WWE Diva Tammy Sytch Challenges Chyna to a Sex-Match!

Tammy Sytch is licking her chops at the release of her celeb porn video that hit the Internet Monday and challenged former wrestler turned porn star Chyna to a match.

Now that she's prime time in the porn world, Tammy's taking the opportunity to challenge her friend Chyna, telling us ... "without a doubt she can kick my ass in the wrestling ring, but I really don't think she stands a chance against me where it matters most. In the bedroom."

Tammy's feeling confident, now that her Vivid Entertainment video "Sunny Side Up" is live on the web, but remember ... Chyna is no stranger to the porn ring.

Tammy even gave her the option of either a one-on-one sex match or they could bring in a man and see who taps out first.

Let the games begin!
