Ricky Martin -- Pitcher?

With a shocked look on his face, gorgeous Ricky Martin got dry-humped by one of his female dancers in Puerto Rico this weekend. He bangs, he bangs!

In some super-tight pants, a blinged-out necklace and sassy belt, Martin shook his hips for a concert at the Coliseo de Puerto Rico on Friday, awkwardly bending one of his backup dancers over on-stage for some raunchy gyrations.

Why does he look so terrified?
