The 30-year-old daughter of Demi Moore and Bruce Willis announced her engagement on Monday, Dec. 23

Tallulah Willis announces engagement to Justin Acee. 

“Everyday @justinacee,” she wrote next to the social media post that began with a sweet photo of her and Acee holding hands over a rose-petal pathway as her engagement band glistened under the night sky.

She followed up the post with a video of her fiancé giving a closer look at the pathway adorned with candles and led from the outside in a Christmas tree-filled living room.

In the third photo, Willis shared a sweet image of the two sharing a kiss in front of one of the holiday trees.

She ended the post with a photo of herself holding her left hand towards the camera, displaying her ring in full view as she cuddled her mom Demi Moore’s tiny pup Pilaf.

“Baby sis is engaged,” Tallulah’s eldest sister Rumer Willis, 36, wrote on her Instagram Stories. She added “Love you so much” and tagged the happy couple. In the caption of Tallulah’s post, Rumer added, “The most beautiful love to witness and watch grow. I love you both so much. Justin I’m so lucky I get to call you my brother. Baby Lula my gift my queen my heart is so full. Obsessed with you both.”

“My angels are engagedddddddddddddd,” middle sister Scout Willis, 33, posted on her Stories, along with teary eyed and diamond ring emojis.

Emma Hemming Willis, their stepmother, simply posted “❤️❤️” — two red heart emojis side by side.

The post received additional celebratory comments, including from Amanda de Cadenet, who wrote, “Crying right now !!!! And so happy for you little Lulah with the sweetest heart ❤️.” Cazzie David commented, “Lulah!!!!!! So happy for you!!!!”

While it is unclear when the two first began dating, Willis was previously engaged to director Dillon Buss. After announcing the engagement in May 2021, she confirmed in a May 2023 essay for Vogue that they had called things off in June 2022. By then she was also navigating her father Bruce Willis’ health issues. The family announced in early 2022 that Willis was suffering from aphasia, and later shared he had been diagnosed with frontotemporal dementia (FTD), a progressive neurological disorder.

Speaking about how Acee has helped her deal with her father’s condition, she told PEOPLE in August: “Waking up laughing with my partner [musician Justin Acee] would be the best kind of day, which I will be honest happens a lot.”

“And then we’ll take my two bigger dogs on a walk around the neighborhood, which if you hit it around the right time, it’s kind of like a dog city hour,” she said.

Earlier this month, while gushing about his latest music video on Instagram, Willis wrote, “Justin is like the gangly freckled knight in shining Bode that I always dreamed of. I’m literally so in love with this dreamboat @justinacee.”

Representatives for Willis did not immediately respond to PEOPLE’s request for comment.
