Mathew Knowles and Beyoncé

*If you believe the NY Post, there’s a big rift developing between Beyoncé and her father and manager, Mathew Knowles.

The Grammy winning singer reportedly is still refusing to speak to him since he became a baby daddy with a woman 20 years his junior. Now execs at her label, Columbia, are fearful the problems between the two could damage her career:

The superstar singer was horrified when it was alleged last year that Matthew had an 18-month affair with 38-year-old Alexsandra Wright and DNA tests confirmed he’d fathered her son, Nixon, while still married to Beyoncé’s mother, Tina Knowles.

Matthew guided Beyoncé’s career through her days with Destiny’s Child and is still her manager.

But one music industry insider said, “Beyoncé was horrified to find out her dad cheated on her mom. She always looked up to him, and she is very close to her mom, so this has hit her really hard. She is refusing to speak to him, which is making things difficult where it comes to managing her career. Some people at Columbia now think it would be better to move him aside.”
