The 34-year-old entertainer took to her Instagram to pay tribute to her dad and share some sweet family photos.
“I can’t believe I’m even writing this….But it is with heavy heart that I share that my sweet sweet Papa left this earth yesterday morning. We as a family are completely heartbroken and devastated,” Katharine wrote.
She added, “He was my biggest fan, my biggest champion, always telling me to ‘Give em hell kid!’ He was so kind and caring and made sure we knew how much he loved us. Not sure my heart will ever be the same. I’m so sad he missed my Broadway debut. But when I return to the stage next week I hope he can watch it in peace and from up above. Thank you to all my friends who’ve been so loving and supportive these last 48 hours. I love you Papa. I already miss you so much. This hurts. 💔”
Our thoughts are with Katherine and her family during this difficult time.
