Beyonce and Jay Z are allegedly heading for a $1 billion divorce. The couple are reportedly fighting over his alleged secret son, Rymir Satterthwaite.

According to Radar Online, the Halo hitmaker was upset after it was revealed that Satterthwaite's mother Wanda was a teenager when she got pregnant. An alleged source said: "Jay and Bey's marriage is blowing up. They're living separate lives. They haven't made an official announcement because Bey isn't ready."

It was previously claimed that Beyonce and Jay Z have secretly split numerous times. The singer's cousin, Shanica Knowles had opened up about the couple's marriage.

"Beyonce has been encouraged to write about the affair rumours to help her deal with it all and help her determine whether she could work through everything or have to end the marriage," Shanica told Heat magazine.

"This has been a long process and I've heard they've had to deal with silent separations and splits over the past few years, but Bey is praying this album will actually save her marriage," she added.

Shanica continued: "She's been through the intense anger and I think she's now learning to forgive Jay. The next few months are going to be the test - this is make or break for them - but he's determined to do everything she can to make it work."
