Pink honored her late father, Jim Moore, on what would've been his 76th birthday on Friday.
Taking to Instagram, the singer shared a photo of his grave and reflected on the complicated relationship she had with him.
"I don't even know that I can handle the cold hard truth that I miss you yet," she wrote. "I wanna still act like this is one of those times that I'm busy and not calling. I can't feel this yet."
"I don't know where you are," she continued. "And therefore I don't know where I am either. Happy Birthday Daddy Sir. Gone but not forgotten. I won't miss you yet. I'm not ready."
Pink first hinted of her father's passing in August when she shared two photos to Instagram of herself dancing with her dad, one at her wedding to husband Carey Hart and the other of a young Pink and Moore at a formal function.
She captioned it, "Til forever."
She'd previously revealed in June 2020 that her father was battling cancer, sharing on Instagram a photo of Moore smiling while undergoing his second round of chemotherapy, noting that he learned he had cancer after he "fell off a ladder and fractured his back."
Pink, whose parents divorced when she was 10, helped her dad realize his music dreams in the mid-2000s when they recorded "I Have Seen the Rain" -- a song Moore wrote while he was serving in the Vietnam War -- together.
She credited her dad's song with helping her learn to play the acoustic guitar and how to harmonize, since it was the first song she ever learned.
The song was a hidden track on her 2006 album, "I'm Not Dead."
