Anderson got mad when Rock delayed a visit to her on the set of her movie in Canada so he could attend a Los Angeles Lakers game, the 36-year-old singer tells Rolling Stone magazine.
"I'm like, 'Baby, I got these tickets. I'll see you on the weekend there,' and that leads into her saying, 'You don't care about me, blah blah blah,' " Rock says. "She finally comes up with this: 'I just had a miscarriage' ... and hangs the phone up."
In November 2006, Anderson's then-publicist issued a statement confirming reports she had a miscarriage and asked that "everyone respect her privacy during this difficult time."
But, Rock says, when he got to Vancouver, "She's partying at this restaurant, drinking champagne, jumping on the tables. I'm thinking, 'That's a quick recovery from a miscarriage.' "
Rock filed for divorce from Anderson a month later, ending their four-month marriage.
Anderson's new rep didn't immediately respond for comment. But in the Rolling Stone article, the actress says: "I hope his album does well. I hope he's happy in life. We were married for four months. If he has nothing nice to say about me, then please tell him to stop talking about me."
Rock's new album, Rock N Roll Jesus, comes out next week.
Pam Calls Rock 'Bitter'Anderson, 40, who recently applied for a wedding license to marry Rick Salomon, said on her on her Web site last week that she had been "getting calls from all over the world" about Rock's statements about her.
"He's bitter," she writes. "It's sad to see. I don't want to battle with him. I wish him the best. I'd hate to point out habits I had a hard time with. They are personal to him and that's why we are not together. These are desperate attempts. I've moved on."
Rock recently made news when he got into a shoving match with Anderson's other ex-husband, Tommy Lee, 45, at the MTV Video Music Awards.
On her Web site Wednesday, meanwhile, Anderson shot down rumors she was pregnant.
"Just very happy," she writes under the headline "Not pregnant." "Started ozone therapy. Healthy as can be. Very exciting."
