NBA star LeBron James is known for his strong family values and his lifelong bond to former high school teammates whom he refers to as brothers.

But according to family insiders, James continues to turn his back on his own brother, Aaron, pictured right.

Family insiders tell Obnoxious blog that Aaron, who was sired by LeBron’s father after he abandoned LeBron’s mother, is struggling to make ends meet.

Now family members say LeBron refuses to acknowledge Aaron, who could pass for his twin.

LeBron has never publicly acknowledged his biological father either. But despite being raised by a single mother, LeBron is the exception to the rule who puts family above everything.

Rhymeswithsnitch.com — The insider claims although Aaron and LeBron never had a relationship, after Aaron’s mother died of cancer last year he struggled to bury her and reluctantly reached out to his famous half-sibling for help.

He never heard back.

The source claims, “You read about all of the things [Lebron James] does in the community and for total strangers, but he does not give a damn about his own brother.”
