Katharine McPhee's Father Passes Away 2 Weeks After Her Engagement To David Foster

Katharine McPhee's father, Daniel McPhee, has died.

The American Idol alum and Broadway star took to Instagram in the early hours of Tuesday, July 17, 2018, to share some devastating news with her fans. Posting photos of herself with her dad, McPhee revealed that Daniel had passed away the day before. "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," she wrote in the picture's caption. "We as a family are completely heartbroken and devastated."

McPhee 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."

Noting that she was upset that he hadn't been able to witness her debut on Broadway in Waitress, she expressed hope that he "can watch it in peace and from up above." After thanking everyone for their love and support during this tough time, she wrote, "I love you Papa. I already miss you so much. This hurts."

McPhee had previously hinted that something was wrong when she tweeted on July 14 that she would not be performing in Waitress during shows over the weekend, as she had to fly to Los Angeles for a family emergency.

News of Daniel's passing comes just two weeks after McPhee announced her engagement to music producer and ex-husband of Real Housewives star Yolanda Hadid, David Foster. As Nicki Swift previously reported, Foster proposed to McPhee while the two were vacationing in Capri in early July.

Opening up about their relationship, Foster told Access Live just how happy he and McPhee are together, noting that "for some reason, the two of us, one plus one makes four instead of two." While we can't exactly support his math, we get the sentiment, and we're sure McPhee's glad to have Foster in her life, especially during this difficult time.

Our thoughts are with McPhee and all those who loved her father as they mourn his passing.
