USA Today published some "highlights" from trash-talkin' poison pen biographer Kitty Kelley's new book, Oprah: A Biography.

Winfrey's falling-outs with friends on the set of The Color Purple:

"She forged strong friendships on the set, but few survived the passage of time," Kelley writes. She "fell out" with Whoopi Goldberg, "tangled" with screenwriter Akosua Busia, "pulled away" from Alice Walker and "offended" Steven Spielberg.

Celebrities comment on whether Winfrey and best friend Gayle King are lesbian partners: 

"I think they are the emotional equivalent of a gay couple," says Rosie O'Donnell, who is gay. "When they did that road trip together that's as gay as it gets and I don't mean it to be an insult either. I'm just saying listen, if you ask me, that's a gay couple." (The quote comes from O'Donnell's appearance on The Howard Stern Show in October 2009.)

Winfrey confidante and author Erica Jong adds: "I would not be surprised if Oprah is gay. If she is, she is. It certainly fits."

Is boyfriend Stedman Graham just a front, 'camouflage'?

"Her close friends argued otherwise, saying he was the grounding force of her life. Others did not care one way or the other," Kelley writes. 

"Stedman is probably gay or neutral, but they have a bond. ... Her being gay would be the right reaction to the sexual abuse she says she's suffered and the mistrust she's always had of men," Winfrey's longtime friend Jong says.
