Meet Beyonce's Half Brother Who Lives On Food Stamps To Survive

Beyonce's Half Brother.

Beyonce's dad is so far behind on child support payments for his illegitimate kid ... his baby mama is destitute and has to use food stamps to survive.
We're told Alexsandra Wright hasn't seen any money from Mathew Knowles since we posted our story back in December -- when he allegedly owed $24K. We're told he now owes $32,135.90. Wright -- whose son is Beyonce's half-brother -- is now on public assistance ... and gets $300 a month on a state-issued EBT card to pay for food and other expenses. Sources tell us Wright went to court for help ... but the judge is noodling over exactly what to do. As we previously reported ... Knowles insists he's not a deadbeat dad ... and has blamed a clerical error for the delinquency. TMZ.
