Tina Knowles filed for divorce from her husband Matthew in Harris County, Texas, In Touch reported Friday. The divorce filing follows a paternity claim made against the pop singer's father.
Matthew Knowles was the target of an October paternity case in which a woman, whose identity was not released, alleged he was the father of her unborn child.
Matthew Knowles, who also serves as Beyonce's manager, and his wife have been married 29 years.
In Touch said the couple also have another daughter, singer Solange Knowles.
