Tallulah Willis is ready to walk down the aisle!

On Monday, December 23, the 30-year-old announced on Instagram that she was marrying her partner Justin Acee.

“Everyday @justinacee,” she wrote alongside the social media post, which began with a sweet photo of her and Acee holding hands, floating above a path of rose petals as her engagement ring glitters under the night sky.

She followed the post with a video in which her fiancé takes a closer look at the candle-decorated path from the outside into a living room decorated with Christmas trees.

In the third photo, Willis shared a sweet picture of the two kissing in front of one of the Christmas trees.

She ended the post with a photo of herself holding her left hand towards the camera, her ring visible, while cuddling her mother Demi Moore’s little puppy Pilaf.

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

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

Emma Heming Willis, her stepmother, simply posted “❤️❤️” – two red heart emojis next to each other.

The post received other celebratory comments, including from Amanda de Cadenet, who wrote: “I’m crying right now!!!! And so happy for you, little Lulah with the sweetest heart ❤️.” Cazzie David commented: “Lulah!!!!!! I’m so happy for you!!!!”

Although it’s unclear when the two first started dating, Willis was previously engaged to director Dillon Buss. After announcing the engagement in May 2021, she confirmed it in a May 2023 essay fashion that they had called the matter off in June 2022. At this time, she was also struggling with her father Bruce Willis’ health problems. The family announced in early 2022 that Willis suffered from aphasia and later shared that he had been diagnosed with frontotemporal dementia (FTD), a progressive neurological disorder.

Speaking about how Acee helped her deal with her father’s illness, she told PEOPLE in August: “Waking up laughing with my partner (musician Justin Acee) would be the best day, and I have to be honest, that’s coming often.”

“And then we go for a walk around the neighborhood with my two bigger dogs, which, if you hit it at the right time, is like an hour in dog town,” she said.

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