Cameron Diaz is dating Alex Rodriguez.

The 'Charlie's Angels' actress has reportedly embarked on a low-key romance with the baseball star - who is nicknamed 'A-Rod' - 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."

The relationship is still in its early stages and is said to be "casual" with neither the sportsman or Cameron looking for a serious commitment.

It was previously reported that the 37-year-old actress had been dancing and "grinding" with Alex, 34, at the Super Bowl party.

The New York Yankees player 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 has been single since splitting from actress Kate Hudson in December.

Cameron has previously dated a host of famous men including Maroon 5 star Adam Levine, musician John Mayer and British model Paul Sculfor.
