Are Beyonce and Jay Z's marriage on the rocks? Rumor has it the power couple is heading for a divorce.

According to Celeb Dirty Laundry, Beyonce and Jay Z's marriage is about to end. The rapper and entrepreneur's alleged love child, Rymir Satterthwaite, has allegedly caused a strain on their relationship. Rymir's mother, Wanda, had called for Jay to get a DNA test for years but the rapper has always declined. She claimed that they had a "fling" in the 90s, when he was still known as Shawn Carter.

Meanwhile, journalist Randy Taraborrelli's new tell-all book would reportedly reveal all the secrets of Beyonce and Jay Z's marriage. He was said to be working on investigating the power couple's "claims of cheating, a lovechild, drug use and dirty business dealings."

Taraborrelli revealed that Beyonce and Jay Z were arguing so much while they were "On The Run" tour that they needed a therapist to save the relationship.

"There's even been allegations that they've split three times in the past four years- and discussed divorce each time!" the journalist added.

The website reported that Randy Taraborrelli's unauthorized biography, titled "Becoming Beyonce" will reportedly focus on the reasons why Beyonce wanted to file a divorce. Rumor has it, Jay Z has been cheating on Beyonce "non-stop" with different women which pushed her over the edge.

"There's juicy stuff about Rita Ora. And about inappropriateness with Rachel Roy."

"People will get to know the real couple -- and Beyoncé is terrified. The book could prove her marriage is, and has been, in shambles," the source added.

Aside from divorce rumors, "Becoming Beyonce" will also touch on the "Love On Top" singer's "sketchy business deals" which will surprise a lot of her fans.

"Beyoncé has lived a most incredible, inspiring life. I know my readers will enjoy her journey," Taraborrelli said.
