The author of Beyonce’s unauthorized biography is making his rounds and speaking on some of the biggest rumors surrounding the singer.

Beyonce & Jay Z Split For A Year After Rihanna Drama, Is She The Cause Of Elevator-Gate?

J. Randy Taraborrelli stopped by The Wendy Williams Show Tuesday and opened up about what fans can expect to read about in the highly anticipated Becoming Beyonce.

He told Williams that fans can thank her for that before speaking on speculation that Beyonce was “jealous” of singer Jennifer Hudson after she became the star and even won an Oscar for their movie Dreamgirls.

Beyonce’s First Love Says She Was A ‘Control Freak’ In A New Interview

“When that movie was made, we all thought Beyonce was going to be the star. She and her team expected she would be the star. I would say it’s overstating to say that she was jealous of her. She was more surprised. When people do movies together, that doesn’t make them friends, that just makes them co-stars in movie.”

He also confirmed that he will touch on speculation that Rihanna’s publicist made up rumors that Jay Z cheated on Beyonce with Rihanna in the early stages of Rihanna’s career.

“It was a story planted in the press that was not true. It was a story he planted to further Rihanna’s career. They did not do the nasty. The publicist [for Rihanna] has apologized publicly to Beyonce for having planted that rumor. He just made the apology over the weekend."

As far as the whole situation when Beyonce’s sister, Solange Knowles, attacked Jay Z (allegedly over a party he wanted to go to in which Rihanna would be there), Taraborrelli said “[Solange] has always been that way” since they were younger.

When it comes to her father, Mathew Knowles, cheating on her mother, Tina Knowles, and even fathering two children in the last year of their marriage, he said “she’s not thrilled about it” but still learned plenty about marriage. Which is why she would not let Jay Z get away with cheating on her like rumors suggest.

“She won’t put up with that in her own marriage.”
