Both parents have played a pivotal role in Beyoncé's career, with Mathew quitting his job at IBM nearly 20 years ago to begin managing the singer's early group, Girl's Tyme, which eventually morphed into Destiny's Child. He has had producer credits on many of Beyoncé's projects, including the 2009 film "Obsessed," and he is the founder of Music World Entertainment, a label that, through Columbia Records, has released albums by Beyoncé, sister Solange Knowles, Sunshine Anderson, and former DC members Kelly Rowland and Michelle Williams.
Tina Knowles is a stylist and one of the principals in House of Dereon, a fashion line she helped launched in 2004 with Beyoncé. She also designed many of DC's one-of-a-kind costumes early in their career.
Mathew was reportedly hit with a paternity suit in October from a woman named Alexsandra Wright, who was then six months pregnant with a child she claimed was Knowles'. It's unclear if that action precipitated the reported divorce filing, according to TMZ.
