Pinkis honoring her late fatherJim Mooreon his birthday, seven weeks after the Vietnam veteran died following a battle with prostate cancer.

The “Just Like A Pill” singer, 42, shared an image of her father’s grave — still awaiting its gravestone and marked with an American flag — with a stack of chocolate doughnuts and a birthday candle on the grass.

Written mostly in the style of song lyrics, Pink’s emotional caption said, “I only knew you for 42 years this time / That’s a long time / That’s not that long.”

The singer, born Alecia Beth Moore, then referred to some troublesome times they experienced, writing “I remember our fights first,” before adding that he would “remind me to be gentler, / To remind me that I was / Nicer than that thing I said.”

She continued to say how he would tell her there was “Nature that needed to be revered. Silence that needed to be listened to.”

“I don’t even know that I can handle the cold hard truth that I miss you yet,” the mother of two 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.”

She concluded the message with: “I won’t miss you yet. I’m not ready.”

At the end of August, Pink shared that her father had died, writing “Til forever” on Instagram alongside two black-and-white photos of the father-daughter duo.

Throughout her life and career, the singer had been open about their close bond and the lessons that he taught her throughout her life.

“Today for me is a celebration of something that my dad taught me. And that is ‘to thine own self be true’… There is a power in believing in yourself — you may not be the best that ever did it, you may not be the prettiest or the tallest of the funniest or the most talented,” she said at the time. “If you’re stubborn and you don’t give up and you work really hard — no one else can ever be you.”
