Beyonce's four-year-old half-brother is almost homeless

The mother of Beyonce's four-year-old half-brother has opened up about her financial problems, convinced that the R&B superstar would be horrified to learn her sibling is facing life on the streets.

Alexsandra Wright, the former girlfriend of the singer's father, Mathew Knowles, tells In Touch magazine that she's considering moving into a homeless shelter with her son Nixon.

She claims that she cannot afford a home now her ex's child support payments have been retroactively reduced from $12,000 to $2,400 -a-month, and doesn't have to hand over a single dime for almost two years.

But Wright thinks that could all change if Beyonce really knew about her plight - and met her half-brother.

She tells the publication, "Nixon deserves to know his family, and I hope one day he will meet his sister Beyonce... I can't imagine how Beyonce feels knowing she has a homeless brother. I know if I were in the same position, I would reach out. Maybe she is too busy."
