Pink is in mourning.

The star took to Instagram on Thursday to share that her father, Jim, has passed away.

To mark the sad occasion, the singer shared two black-and-white photos of her dancing with her father while dressed to the nines. One showed the duo when Pink was just a child while the other was more recent.

"Til forever," the musician, born Alecia Moore, wrote in the caption.

"My wonderful dad just passed away on Sunday," one said. "I know exactly how you’re feeling. It’s so hard. There are no words to make it better. Just know there are people holding you in their thoughts."

"It's not goodbye it's just see you later," wrote another.

A third added: "Sending love & Light to you, Hubby your Momma, your brother & kids & the rest of the family who’s mourning this beautiful soul. Rest in leave sir."

"This is very hard I just lost my dad 4 months ago and I miss him every day every second it hurts, I am sorry your going thru this heartbreaking loss," yet another said.

Pink did not make mention of her father's cause of death, but she revealed last year on Instagram that he was undergoing chemotherapy for prostate cancer and had faced several other health concerns.

Reps for the singer did not immediately respond to Fox News' request for comment.

According to People magazine, the star performed a song that her father wrote about his time serving in Vietnam.

"He wrote a song about 40 years ago in Vietnam and I think it's important today because it's a soldier cry," she said at the time, referring to her father as "favorite person in the whole world."

When she announced her father's cancer battle – and subsequent tumble off a ladder resulting in several injuries – Pink noted that she loved her father "with all of my heart" and noted "how amazing it is to watch you whistle through Hell."
