Rumer Willis reveals she will 'treasure' first photo of Bruce Willis holding her baby on Father's Day

Rumer Willis has shared a sweet photo with Bruce Willis holding his first granddaughter on Father’s Day.

She took to Instagram to share a picture of her dad holding her daughter Louetta on the annual day.

“Seeing my father hold my daughter today was something I will treasure for the rest of my life. His sweetness and love for her was so pure and beautiful,” she said.

“Papa I’m so lucky to have you and so is Lou. Thank you for being the silliest, most loving, coolest Daddio a girl could ask for. Best Girl Dad in the game.”

Many fans shared heartfelt messages to congratulate Bruce on his new grandfather status.

One person wrote: “Aww, and her looking at your dad in that second picture is priceless!!”

Another said: “There’s so much love in your family… thank you for sharing your world.”

While a third marveled: “That pic of Lou looking at your Dad, Priceless! She knows how much she is loved and how much love she will (already has) give him. The love we have for grandchildren is unexplainable!”

Rumer also wished her baby daddy, Derek Thomas, a happy Father’s Day for the first time since the couple welcomed their baby girl in April this year.

Bruce’s wife, Emma Hemming, also shared a tribute to the actor on Father’s Day, posting a photo with the older daughter, Mabel, 11.

In the post, the father-daughter duo sat on a wicker seat as Mabel snuggled up to Bruce as he kissed her forehead.

“Father’s Day is a time I get to reflect on my deep appreciation and respect I have for Bruce as I watch him father our little ones. Where it might not be 'conventional,' what he’s teaching them will span generations. Unconditional love, kindness, strength, compassion, patience, generosity, resilience,” she wrote.

“Happy Father’s Day to the greatest dad I know, who will forever be the gift that keeps giving within our family."

In February, Bruce’s family revealed that he was officially diagnosed with frontotemporal dementia (FTD).

FTD impacts the lobes of the brain behind the forehead, with symptoms including personality changes, obsessive behavior and speaking difficulties common.

In March, Hemming shared an emotional video of a montage of the actor on his 68th birthday, explaining that it’s painful to celebrate days like this when her husband struggles with dementia.

Hemming added that while watching the videos felt like 'a knife in her heart’, she wanted to share the videos so that fans could celebrate him too.

She said: “So I worked on this reel that I'm posting for my husband's birthday. I don't know why I do that because the videos are like a knife in my heart.

"But as much as I do it for myself I do it for you.”
