Rumer Willis is reminiscing on her childhood and her close bond with father, Bruce Willis.

On Thursday, the actress shared a throwback photo of her father, now 67, giving her a kiss on the forehead when she was a young girl.

The "Once Upon a Time in Hollywood" star, 33, captioned the photo, "P A P A."

Rumer's sweet photo comes weeks after she took to social media to thank her dad for "teaching me to be so silly" after the "Die Hard" actor's family announced he is stepping away from his acting career following his aphasia diagnosis.

Aphasia is a condition that causes a loss of the ability to understand or express speech. In an announcement shared on social media, Bruce's wife, Emma Heming Willis, his ex-wife, Demi Moore, and his five children, Rumer, Scout, Tallulah, Mabel and Evelyn shared that the condition has been impacting his cognitive abilities.

"We are moving through this as a strong family unit, and wanted to bring his fans in because we know how much he means to you, as you do to him," they said. "As Bruce always says, ‘Live it up’ and together we plan to do just that."

There are many potential causes of aphasia. It often occurs after a stroke or head injury, but can also develop gradually due to a slow-growing brain tumor or a disease that causes degenerative damage, like Alzheimer’s disease. It’s treated primarily with speech therapy and learning non-verbal means of communication.

Willis’ family didn’t divulge what caused his aphasia. Representatives for the actor have declined to comment.

"Mom & Dad in their favorite habitat," Heming captioned the post, along with the hashtag #offthegrid.

The first photo showed Willis and his wife gazing into each other's eyes and smiling while sitting on a big tree trunk in the woods. In another snapshot, Heming, 43, has her head on one of Willis' shoulders.
