Maureen McCormick, better known as Marcia Brady on the sitcom 'Brady Bunch', has a new book coming out. The book is said to having shocking details of a lesbian fling with Eve Plumb who played her sister on the show Jan Brady.

The National Enquirer had a quote from an unnamed source stating:

'This book will certainly come as a shocker. While Maureen is not a lesbian, she reveals there were some sexual hi jinks going on behind the scenes. It's bizarre because she played such a virginal character on the show.'

Marcia, Marcia , Marcia !

'Here's The Story', McCormick's autobiography, is set to be released next year.
