Gay governor's wife had no idea!

This may not come as a surprise to anyone, but...  gay governor James McGreevey's estranged wife didn't know he was having a gay affair while they were married.

According to the ghostwriter of Dina Matos McGreevey's upcoming tell-all memoir, she had no clue that her man was screwing other men then coming home to crawl in the bed with her.

Elizabeth Stone, the uncredited co-author of "Silent Partner," due out May 1 by Hyperion, spoke about her experience Saturday during a Fordham University panel discussion on memoir writing for students and alumni, The Star-Ledger of Newark reported Sunday.

This is the first time anyone has heard from Matos McGreevey since she stood behind her husband, then New Jersey governor, as he announced he was a "gay American."

"Dina McGreevey lived 10 years with a man who was gay, but she didn't know he was gay," said Stone, who teaches English and journalism at Fordham. "People who have loved ones who betray them: What do they do when they find out? They have to go back and re-experience."

In an excerpt Stone read from the book, Matos McGreevey, 40, said the book has been a "healing venture" and urges people to "tell others your story as I tell you mine. Don't let others tell you."

Stone also said Matos doesn't really believe that McGreevey is actually gay, she thinks he's bisexual.  Maybe he's on the bi now gay later program.
