Is Beyonce a "control freak"?

J. Randy Taraborrelli's upcoming unauthorized biography, Becoming Beyoncé, is causing major controversy amongst Queen Bey fans. The author claims that the 34-year-old pop star has a controlling side, especially when it comes to her 3-year-old daughter Blue Ivy's nannies.

"She's really a control freak, let's be honest," Taraborrelli told ET about the book's claims that nannies must sign a contract that includes stipulations like not allowing Blue Ivy to fall asleep to music. "So if you're a nanny coming into her household you have to adhere to this."

Taraborrelli doesn't fan the flames on all of the gossip, however. The author shut down rumors of Jay Z's rumored past infidelities, which included an alleged affair with Rihanna when the "Pon de Replay" singer was first starting out.

"To all the people out there who believe that Jay Z cheats on Beyonce and that she allows it, I can tell you that's not gonna happen," he said. "Beyonce is not that way."

The author goes onto claim that the Jay Z/ Rihanna fling rumors were actually put forth by a publicist.

Taraborelli even claims that the couple's infamous "elevator incident" in 2014 occured when Beyonce's sister, Solange Knowles, overheard the two arguing about Jay Z wanting to go to a party with Rihanna.

"Beyonce did what Beyonce does: she laid down the law. This is very Beyonce, to say, 'You ain't going. It's not gonna happen. End of story.'"
