Continuing, theAmerican Idolalum added: “And now I’m ready to share with all of you what has been my sunshine amongst this painful loss. My love wisely said to me the other day that ‘death is the only thing that is 100 percent inevitable and the thing we are least prepared for.’ So today we’re celebrating life and not forgetting love.”

McPhee announced on Monday that her father had passed away the previous morning.

“I can’t believe I’m even writing this,” she wrote on social media alongside a picture of the pair. “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. 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,” she continued. “I love you Papa.I already miss you so much. This hurts.”
