On Sunday, actress Demi Moore shared a very sweet video of Bruce Willis and his entire family as they celebrate his birthday. The celebration comes a month after his family announced his diagnosis of frontotemporal dementia (known as FTD.)

It hasn’t been an easy year for Willis and his family, after battling aphasia for an unspecified amount of time the legendary actor was officially diagnosed with FTD recently. The condition is known to affect a person’s behavior, speech, language and memory. He officially retired from acting last March, when his wife, Emma Heming Willis and the rest of Willis’ family shared he was suffering from aphasia.

But he and the fam were all smiles during his 68th birthday celebration this weekend, and Moore shared the most heartwarming video to prove it. The whole family singing “Happy Birthday” while Bruce sings along and clearly has a blast blowing out those candles? Priceless.

Moore wrote: “Happy birthday, BW! So glad we could celebrate you today. Love you and love our family. Thank you to everyone for the love and warm wishes – we all feel them.”

And while this celebration is certainly something to feel joy about, it’s important to remember that nothing about this journey is easy for his family—particularly his wife and caregiver, Emma Heming Willis. Heming Willis shared a video of her own for her husband’s birthday, where she shared the vulnerable and heartbreaking truth of how bittersweet it all is, especially when she feels a lot of grief.

“I have started the morning by crying, as you can see by my swollen eyes,” she said her own Bruce Willis birthday video.

“It’s important that you see all sides of this,” she explained. “I always get this message where people always tell me, ‘Oh you’re so strong. I don’t know how you do it.’ I’m not given a choice. I wish I was but I’m also raising two kids in this.”

As someone who also has experience as a spouse, caregiver and mother to young kids—her words are impactful and necessary.

“Sometimes in our lives, we have to put our big girl panties on and get to it, and that’s what I’m doing,” she says. “But I do have times of sadness every day, grief every day and I’m really feeling it today on his birthday.”

While the diagnosis of FTD is a devastating one, the Willis family shared that by sharing Bruce’s diagnosis, it will shine a light on the disease.

“FTD is a cruel disease that many of us have never heard of and can strike anyone,” the statement, released last month, reads. “For people under 60, FTD is the most common form of dementia, and because getting the diagnosis can take years, FTD is likely much more prevalent than we know. Today there are no treatments for the disease, a reality that we hope can change in the years ahead. As Bruce’s condition advances, we hope that any media attention can be focused on shining a light on this disease that needs far more awareness and research.”
