Don’t tell Madonna, but New York Yankees third baseman Alex Rodriguez was spotted getting cozy with Hollywood actress Cameron Diaz at a Pre-Super Bowl party in Miami last weekend!

Cameron was spied humping on A-Rod at the CAA Party on Saturday night, fellow revellers gab to OK! Magazine.

Spies say Rodriguez was sitting on a couch beside Cameron as she “was dancing by herself” before moving her gyrating body towards him.

At one point the blonde beauty – who was “tipsy” and being very “fun and flirty” – began “grinding on ‘A-Rod.’”

Alex recently ended his romance with screen star Kate Hudson.
