Beyoncé has a younger sister and a younger half-brother. Her younger sister is Solange Knowles, who was born in 1986. Her younger half-brother, Nixon, born in 2010, is the child of Beyoncé's father and the actress Alexsandra Wright.
Beyoncé and Solange Knowles' parents are music executive Mathew Knowles and his ex-wife Tina Knowles. Their mother filed for divorce after reports surfaced of their father's affair. Mathew Knowles denied paternity at first, but a DNA test proved that he was Nixon's father. Mathew had managed both Beyoncé and Solange's careers starting when they were young, but Beyoncé terminated her business ties with her father in 2011.
