Stay strong. Beyoncé‘s father, Mathew Knowles, has unfortunately been diagnosed with breast cancer, but he’s not giving up without a fight. While chatting with Michael Strahan on Good Morning America, Mathew revealed how the disease has impacted his life during a candid interview which is scheduled to air on Wednesday, October 2.

“How was it to tell your family about the diagnosis?” Michael asked during their sit-down conversation in the teaser which dropped on Tuesday, October 1. The 67-year-old appears to share how his loved ones helped him cope with the news.

As fans may recall, Mathew was previously married to Tina Knowles for 31 years, having welcomed Beyoncé and Solange while they were still together. The couple ultimately called it quits and their divorce was announced in 2011. After their split, Tina went on to marry actor Richard Lawson, while he’s now wed to Gena Charmaine Avery.

Back in 2016, Solange featured her father’s voice on an interlude for her award-winning album A Seat At The Table. She later opened up about the experience of reconnecting with her dad and how much it meant to her.

“Obviously, my parents are divorced, and getting the two of them in a room together was a powerful moment in time,” Solange told Billboard. “They really led the conversation. I felt that because of my yearning to know, they were honest with me.”

Over the years, Mathew has discussed how proud he is of his daughters, having recently discussed Beyoncé’s chart-topping alum Lemonade, which became a huge success. “I think that’s the beauty of her creativity and I think that’s what makes it so special, is that it relates to everyone,” he told E! News about why he thinks it was such a hit.

“Every one of us have been disappointed before and have had to go through the grieving process of anger and, you know, disappointment and then acceptance and forgiveness,” Mathew added. “And I think that’s why this again is touching so many people, because it’s universal. Everybody can relate to it.”

We’re keeping the Knowles family in our thoughts.

Fans can tune into the full interview tomorrow on Good Morning America.
