Tina Knowles made it her "mission" to protect Beyoncé at the start of her career.
The 70-year-old businesswoman - who is mother to global superstar Beyoncé, 43, with her ex-husband Mathew Knowles - signed up to be the stylist for Destiny's Child when her daughter first made it big in the late 1990s alongside Kelly Rowland and Michelle Williams because she was "determined" to look after them amid their sudden rise to fame.
