Alex Rodriguez has finally spoken out about his ex-girlfriend Cameron Diaz. Using the star’s initials as a term of endearment, A-Rod tells “The Insider” host Kevin Frazier in the show airing tonight: “I don’t like talking about my relationships, but I will tell you about CD: She’s probably one of the greatest human beings I’ve ever met, and just an amazing light.” But when asked about marriage, the divorced Yankee slugger was less enthusiastic. “I’m not sure,” he says. “I think my new hero is George Clooney” — the eternal bachelor whose girlfriend Stacy Keibler is close friends with Rodriguez’s new love Torrie Wilson. “He’s my new role model,” he says of Clooney. “I think he’s done it right.”
