Tallulah Willis, the daughter of US stars Bruce Willis and Demi Moore, has married musician Justin Acee.

The couple, who have been dating since 2023 and announced their engagement in December 2024, tied the knot on Saturday during a ceremony in Sun Valley, Idaho, according to Vogue.

The gown featured a strapless bodice with a draped skirt, a bow on the back and a long train.

Vogue joined Tallulah, her older sisters Rumer and Scout, and their award-winning actress mother for the final dress fitting ahead of the wedding.

“I’m feeling almost out of body. I have my family here, I’m trying on this dress, being in kind of a princess moment,” Willis told the publication.

Moore recounted spending four hours with the designer during their first meeting to discuss the dress, and added: “I think he would have stayed there playing all day.”

Vogue says the elaborate gown took 712 hours of work, including 405 hours of construction and atelier alterations.

An additional nine hours were dedicated to the veil.

Willis added: “The best part of the dress is the magnitude. It’s the thing that’s getting me to my new husband.

“We made a decision at the very beginning of our relationship that we were going to choose each other every day.

“My biggest hope (for the dress) was that (it would be) something magical, but magical in a way that was unexpected, kind of like me.

“I’ve worked very hard to be comfortable in my own skin, to be in something that there’s a strength in is profound for me.

“I’ve worked so hard in my life to be able to find that beauty every day… This is definitely a very special peak celebration moment of beauty.”

Willis’ parents were married from 1987 to 2000.

Her father is a Hollywood star known for films such as Die Hard, The Sixth Sense and Pulp Fiction, but has stepped away from his acting career amid his health struggles.

He has been married to model Emma Heming Willis for 17 years, with whom he has two children.

Moore is famed for starring in blockbusters such as Ghost, A Few Good Men and Indecent Proposal, and has won many major acting awards during her decades-long career.
