American R&B star Beyonce is still very much disappointed with her father Matthew Knowles for cheating on her mother. She refuses to forgive him and wouldn't even bother talking to him.

Bee's dad had an 18-month affair with actress Alexsandra Wright and had a love child with her named Nixon, who was born just four months ago. After a paternity test proved the baby was his, a judge ordered him to pay $8,200 a month in child support.

And now her record label is in a frenzy trying to figure out what to do since Knowles still manages Beyonce's career.

A music industry insider says that executives at Columbia are worried because their relationship has reached such a low point.

"Beyonce 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," the source said.
