The father of musical superstars Beyonce and Solange is revealing his breast cancer diagnosis

In an interview airing Wednesday on “Good Morning America,” Mathew Knowles talks to the host about what it was like to break the news to his family.

The show posted a short clip of the interview on social media Tuesday — the same day he tweeted he’d have a “special announcement” when he appears on the show.

He managed Beyoncé from the late 1990s, when she was in the multiplatinum selling group Destiny’s Child, through the launch of her career as a solo artist after the girl group split in 2006.
Beyoncé cut professional ties with her father in 2011, and both sides said it was amicable.
‘I’ve only parted ways with my father on a business level,” Beyoncé said at the time. “He is my father for life and I love my dad dearly. I am grateful for everything he has taught me.”
