Remember Beyonce dad cheated on her mom while they were married and a child was born from that relationship.

Well Beyonce's parents got divorced and Alexsandra Wright, Mathew's mistress gave birth to a son.

She now says Beyonce's father is no father to her son at all.

In fact, she says she feels betrayed by Mathew Knowles because more than anything she respected him as a friend nd collegue and he's chosen to turn his back.
