Back in 2010 it was revealed that Mathew Knowles had secretly fathered a child outside his marriage to Tina Knowles.

Now, for the first time, Mathew’s baby mama speaks out claiming she’s very disappointed in Mathew Knowles and that Beyonce is not responsible for her son…

Alexsandra Wright tells Inside Edition,

“It’s disappointing. I’m not angry. I’m disappointed. More than anything he raised two other children and was very active and involved in their lives and they turned out very well, so why he’s choosing not to acknowledge his only son, I don’t know, but it’s disappointing…”

“I am the only parent taking accountably at this point. It’s not anybody else’s responsibility but Mathew Knowles….”

“I don’t expect Beyonce to take accountability. It’s not her problem Its not her situation.” I’am really getting sick of her!!”
