The New York Post is reporting that Cameron Diaz and MLB slugger Alex Rodriguez are becoming quite close.

The 'Charlie's Angels' actress has reportedly embarked on a low-key romance with the baseball star after they met at a Creative Artists Agency Super Bowl party in February.

A source told Life and Style magazine: "A-Rod is with Cameron. They've been keeping it quiet, but they're totally together."

Apparently the relationship is still in its early stages and is said to be "casual," with neither A-Rod or Cameron looking for a serious commitment.
