Exclusive! Alex Rodriguez Shirtless!

NY Yankees slugger Alex ‘A-Rod’ Rodriguez spent yesterday cruising around the waters of Miami Beach on a luxury yacht with a mystery blond.  A-Rod, who was previously linked to Madonna and Kate Hudson, enjoyed the Florida sunshine shirtless (SWOON!) on the bow of the yacht while his companion donned a string bikini top but keep it covered up with a hoody.

The pair arrived at the marina separately and left at the end of their  day trip separately. Wonder if he was trying to keep their meeting under wraps?
