A-ROD BREAKS UP WITH CAMERON DIAZ!

Alex Rodriguez might've lost his chance at another World Series ring last month but he also lost something else: girlfriend Cameron Diaz.
The difference?

While A-Rod presumably didn't want to fall short in the Fall Classic, Life & Style reports that it was his choice to call it quits with the romance.

"Cameron and A-Rod are no longer dating and have definitely parted ways," a source told the mag. "He just doesn't like her anymore. That's honestly the reason they split."

Rodriguez and Diaz began dating in February, making sly appearances together throughout the country but never verbally confirming the relationship.

But in October, each began stepping out without the other.

Diaz, 38, was recently seen out with a mystery man in London and also hung out with "Glee" star Matthew Morrison.

As for Rodriguez, 35, the Yankees slugger has partied with a bevy of ladies in Las Vegas and Miami.

According to Life & Style, the now former couple was last seen together Sept. 22.
