Alex Rodriguez appears to have a thing for blondes. According to the New York Post, A-Rod, who split with Kate Hudson last year, has had a hush-hush liaison with starlet Cameron Diaz that began when the two flirted at the Creative Artists Agency Super Bowl party in February. Evidently, they later snuck off for a few evenings together in Florida during A-Rod's spring training. An unnamed source said, "they've been keeping it quiet, but they're totally together." Apparently they're casual too, with neither one pushing for a serious commitment.
