Happy birthday to Tallulah Willis, the youngest daughter of actors Bruce Willis and Demi Moore.

On Monday, Tallulah Willis announced on social media that she is engaged to musician Justin Acee.

In an adorable Instagram post, Willis shared photos from the special moment, showing a close-up of a ring and the couple leaning in for a kiss.

She also shared footage that appeared to have been shot by her fiancé as he documented the romantic, holiday-themed scenery of the engagement, including a candle-lit path decorated with rose petals.

Willis, who has launched a clothing line in recent years, captioned her post, “everyday @justinacee” and tagged her boyfriend.

Older sister Rumer Willis celebrated the good news on her Instagram Stories.

“Baby Sis is engaged,” the “Empire” actor wrote as he reposted Monday’s announcement.

Rumer Willis also showed love under her younger sister’s Instagram post, commenting, “It’s 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.”

She added: “Baby Lula, my gift, my queen, my heart is so full. “I’m obsessed with you both.”

Her middle sister, Scout Willis, took to her own Instagram Stories and wrote, “My angels are engagedddddddddddd.”

Like Tallulah Willis, Rumer and Scout Willis are the adult daughters of Bruce Willis and Moore, his ex-wife.

The “Die Hard” actor’s current wife, Emma Heming Willis, also celebrated the announcement of the engagement and posted two heart emojis on Instagram. Bruce Willis married the model in 2009. They share two children, girls Mabel and Evelyn.

This week’s news comes after the Sixth Sense star’s family announced in 2022 that he would be retiring from acting due to an aphasia diagnosis. His family later said the condition, which affects communication, had developed into frontotemporal dementia.
