“Everyday @justinacee,” the “Bandits” actor captioned the post.

In the comments, Tallulah Willis’ older sister Rumer Willis wrote: “It is the most beautiful love to witness and watch grow. I love you both so much. Justin, I’m so happy I get to call you my brother. Baby Lula, my gift.” Queen, my heart is so obsessed with you both.

Bruce Willis’ wife, Emma Heming Willis, commented on the post with two red heart emojis.

Rumer Willis also re-shared the post on her Instagram Story and wrote, “Baby Sis is engaged.”

“I love you so much,” she added.

Tallulah Willis’ other older sister, Scout Willis, also shared some of the engagement photos on her Instagram Story. She wrote about the pictures: “My angels are engageddddddddddddd 🥹🥹🥹🥹.”

Tallulah Willis was engaged to film director Dillon Buss back in 2021. However, in a May 2023 essay for Vogue, she revealed that she was “dumped” by Buss in June 2022.

During this time, Tallulah Willis also dealt with her father’s health issues. In March 2022, her family announced that Bruce Willis suffered from aphasia. Then, in February 2023, the Willis family announced that the actor’s condition had progressed to frontotemporal dementia, a neurodegenerative disease that affects the frontal and temporal lobes of the brain.

In September, Tallulah Willis opened up about her father’s health in an interview with Savannah Guthrie and Hoda Kotb on TODAY.

“He is stable, which is good and difficult in this situation,” she said. “There are painful days, but there is so much love.”
