Katharine McPhee’s dad dies

Katharine McPhee is mourning the loss of her father, Daniel, just weeks after getting engaged to David Foster.

“I can’t believe I’m even writing this….,” the “American Idol” alum wrote on Instagram Tuesday morning. “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.”

She continued, “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.”

The death of McPhee’s father comes shortly after the actress’s engagement to music producer Foster, 68, who proposed while vacationing in Capri, Italy, earlier this month. McPhee penned Saturday she would miss the weekend’s performances of Broadway hit “Waitress” due to a family emergency. She is performing through Aug. 19.

“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,” McPhee penned. “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. 💔”
