Mathew formerly worked as both Beyoncé, 38, and Solange’s managers, and he was also the manager of Destiny’s Child.
While his relationship with Beyoncé is known to have become strained in recent years, the pair now seem to be on good terms.

Last month on September 4, Mathew wished Beyoncé a happy 38th birthday with a sweet tribute on Instagram.
“It’s your birthday! I hope you party like it’s your birthday, @beyoncé! Love, Dad,” he wrote alongside a video compilation of Beyoncé performing.
