Beyoncé Knowles' dad was her manager for two decades—since her Destiny's Child days—until she sacked him. Their relationship was reportedly strained after Matthew Knowles admitted to having an affair with Alexsandra Wright, who gave birth to their child. After the news, Matthew and Beyonce's mother Tina filed for divorce. But Beyoncé insisted the decision had nothing to do with tense family relations. "He is my father and I love my dad dearly," she said, before adding that they were only parting ways on a "business level." She thanked him for his influence on her career (he saw her through three blockbuster solo albums, 16 Grammys, and three major film roles) but Matthew probably won't get a cut of his daughter's latest, A Star Is Born.
