Demi Moore and Emma Heming Team Up for Father's Day Tribute to Bruce Willis

In the two years since Bruce Willis was first diagnosed with the cognitive disorder aphasia, which was later revealed to be frontotemporal dementia, his family has put forth a united front. And that includes his wife of 15 years, Emma Heming Willis, as well as his ex-wife Demi Moore.

So it should come as little surprise that both his current and former wives came together to post a joint Father's Day message to Willis on Sunday.

"Happy Father’s Day to our favorite girl dad. We love you, BW!" the post was captioned, which was likewise cosigned by Willis' three adult daughters with Moore; Rumer, Scout, and Tallulah Willis. The gallery featured 10 photos of the Die Hard star doting on his children throughout the years, which include his two daughters Mabel Ray, 12, and Evelyn Penn, 10, whom he shares with Heming.

Though Willis and Moore officially parted ways in June 1998, and later finalized their divorce on Oct. 18, 2000, the former couple have remained close throughout the years. Willis was even a guest at Moore's wedding to her third husband, Aston Kutcher in September 2005.

Moore has likewise remained by his ex's side in the wake of his diagnosis. Earlier this year, during an appearance on Andy Cohen's SiriusXM show Radio Andy, Moore was asked for advice on what she would tell people who have family members living with dementia.

"I think the most important thing I could share is just to meet them where they’re at," she said in the Jan. 30 interview. "When you let go of who they’ve been or who you think they [should be], or who even you would like them to be, you can then really stay in the present and take in the joy and the love that is present and there for all that they are, not all that they’re not."

While it's impossible to understand how difficult it must be living with his disease, Willis is certainly fortunate for all the love and support he continues to receive.
