Former “Today” show anchor Meredith Vieira won’t be reading Brian Stelter’s dishy new book on her old morning show, “Top of the Morning,” any time soon. “I’m not interested,” Vieira, who’s included in the tome, recently told Page Six. “I’m over it . . . I’ve kind of been-there-done-that, and I don’t know what the interest is.” She added, “I don’t want to get on a high horse, because I understand why people write it. I’m not trying to say he’s wrong to do it, but I look at it and it’s so personal to me. It’s my friends.” Vieira also defended embattled host Matt Lauer, telling us, “Even if [NBC] blew it from a p.r. point of view, you’ve got to move on. I think what is happening to Matt is really wrong.”
