Beyonce's mother, Tina Knowles, 55,  filed for divorce from the pop diva's father and manager, Mathew Knowles, 58. Tina and Matthew have been married for almost 30 years.

The divorce filing came about a month after Mathew Knowles was named in a paternity suit. Los Angeles resident Alexsandra Wright claims in the lawsuit that he is the father of her unborn child.

“The decision to end our marriage is an amicable one. We remain friends, parents, and business partners,” the couple said in a statement provided to The Associated Press. “If anyone is expecting an ugly messy fight, they will be sadly disappointed. We ask for your respect of our privacy as we handle this matter.”

Tina Knowles and Mathew Knowles have been heavily involved in their daughters' careers. Mathew serves as a manager to Beyonce and Solange, while Tina was the costume designer of Beyonce's former music group Destiny's Child, and is currently serving as the creative director for House of Dereon, a fashion label with which Beyonce collaborates.

The couple has two children together: Beyonce, 28, and fellow singer Solange, 23.
