Katharine McPhee Shows Off Engagement Ring: It Was 'the Last Thing I Showed My Dad Before He Passed'

Katharine McPhee's engagement ring will always have special meaning for her, in more ways than one.

McPhee, who recently announced her engagement to music producer David Foster, posted a photo of the ring on Saturday and revealed it was "the last thing I showed my dad before he passed and makes me smile when I look at this as a reminder of our last conversation."

"It’s been a hard week," McPhee wrote, Lots of tears but I want to thank my friends and family for all the love and support. My dad was so happy for me."

She said she's gotten comfort from Foster since her father's passing, writing, "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 her father's passing on Monday, saying, "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!'"
