Maureen McCormick tried to spice up sales of her tell-all book with a little tidbit about her and Eve Plumb having a lesbian affair during their Brady Bunch years. But did Maureen McCormick cost her friendship with her TV sister?

Maureen McCormick blogged this week at Fancast.com about the cast of the Brady Bunch being invited to a reunion on Oprah in September, but Eve Plumb declined. According to McCormick:

“All of us said yes except for one person, Eve Plumb, who used to be my best friend but now apparently wants to distance herself from the show and, most troubling, from me … I have no idea why, unless she’s mad at the joke I made a few years ago that we’d had a lesbian love affair. I made the crack to be funny — and for shock value. I’m sorry if she took offense.”

Apparently, McCormick had made the joke prior to the release of her autobiography, “Here’s the Story.” No doubt the lesbian rumor helped push a few copies.

Eve Plumb’s agent, however, says: “No one from ‘Oprah’ called. We haven’t turned down anything. There is no feud.”
