Beyonce's Little Brother Has Never Met Superstar

INSIDE EDITION has the exclusive report on Beyonce's sibling who has never met the superstar.

This adorable four-year-old boy is Beyoncé's half-brother, but they've never even met.

Now, the mother of Nixon Alexander Knowles is speaking out exclusively to INSIDE EDITION.

Alexsandra Wright told INSIDE EDITION's Jim Moret, "I'm going to stand up, and I'm going to fight tomorrow, and I'm going to fight the next day. I'm going to keep fighting because that's the only way to give him his identity."

Wright claims she'll have to file for public assistance because she says Beyoncé's father, Matthew Knowles hasn't paid $32,000 in court-ordered child support.  

"How much has Matthew Knowles seen his son?" asked Moret.

"You've seen him more today than he has," she answered.

Forty-year-old Alexsandra is a former actress who appeared in a 2001 episode of the TV series Scrubs.

She says she had an 18-month affair with Matthew Knowles, who was married for 31 years to Beyoncé's mother, Tina. When Nixon was born in 2010, a paternity test confirmed Knowles is the father.  

"I tried everything to not have it public. But unfortunately, that's just not the way that Matthew chose to deal with this," said Wright.

The affair tore Beyoncé's family apart. Her mom filed for divorce and Beyoncé fired her dad as manager. The superstar and her father are now estranged.

"I don't expect Beyoncé to take accountability. It's not her problem. It's not her situation," said Wright.

Now get this—Alexsandra claims that Matthew Knowles actually suggested that she hand over their son to Beyoncé and Jay Z so they could raise him as their own before their daughter Blue Ivy was born.

"Beyoncé and Jay Z have never attacked me. They've done anything wrong to me. They've never been negative at all," Wright confirmed.

Matthew Knowles' attorney told INSIDE EDITION he has no comment, but in published reports, Knowles has denied he's a deadbeat dad.

Now, this mom hopes that someday Beyoncé will finally meet her little brother.

Wright stated, "Every time a rock gets thrown and I get knocked down, I get right back up. There's nothing better to fight for than my son."
