He’s got 99 problems and a love child may be one of them… Jay Z is being sued by a 21-year-old man that claims to be his son. Rymir Satterthwaite, an aspiring rapper, claims that music mogul is his biological father and wants Jay Z to take a paternity test to prove it. According to a report in The National Enquirer, Satterthwaite issued a civil lawsuit against Jay Z in a New Jersey civil court in December of last year via his legal guardian, Lillie Coley. The lawsuit alleges that ‘Holy Grail’ hitmaker gave ‘fraudulent’ information to the court in a bid to avoid taking a paternity test. The 45-year-old and wife Beyoncé celebrated the birth of their first child Blue Ivy on January 7th 2012 and if reports are true, she may very well have a big brother. In an interview with Daily News, Satterthwaite's Godmother said that the family plan to bring the matter public soon. “Right now I can't talk to you about it,” she explained. "We plan to talk to the public soon." “All this attention caught us off guard... We didn't expect someone to leak it to the press. We weren't expecting this.”
