Demi Moore couldn’t be happier for her daughter, Tallulah Willis, after her engagement news

And following the good news, Demi posted on her Instagram to congratulate the happy couple.

Posting a picture of herself receiving a kiss on each cheek from Tallulah and Dillon, she wrote: “Congrats to my baby girl and her adorable beloved on their engagement! Happy day for the whole family (sic)”

Tallulah originally announced the news this week when she shared several snaps to her Instagram account which featured Dillon on one knee, and

wrote: “with absolute most certainty (sic)”

She then posted a video in which she showed off her engagement ring, and

added: “HANDS STILL SHAKIN’ — MOMS SPAGHETTI — I’m FIANCÉNCHED (sic)”

Dillon also shared pictures on his own Instagram account, including one of the couple cuddling with Tallulah’s giant sparkler on show.

He captioned his snaps: “I can finally call you my fiancé. Love you forever Buuski Lu, you are my best friend #maythefourthbewithus (sic)”

And Tallulah’s sisters - Scout, 29, and Rumer, 32 – commented on her posts to congratulate her at the time.

Scout wrote: “weeping, i am so f****** excited (sic)”, whilst Rumer

added: "I love these crazy kids. Congratulations @dillonbuss and @buuski I love you both so immensely and I am so excited for you (sic)”

There were also sweet comments from the likes of Arielle Vandenberg, Helena Christensen, Sharna Burgess, Ireland Baldwin, Cazzie David, Kristen Doute, and Nick Viall.

Tallulah and Demi were previously estranged from each other for three years after Tallulah stopped talking to her mother after the 58-year-old actress started drinking and using Vicodin following her split from Ashton Kutcher in 2013.

And Tallulah previously said she felt like "absolute dust" during their estrangement.

Writing on social media to mark Mother’s Day last year, she explained:

"Channeling love and strength to every mother to be, tired mamas, step moms, and mamas who've lost something precious. I'm sending it to anyone who struggles to celebrate a day when it reminds them of a loss.

"I didn't talk to my mom for almost 3 years and during that shattered time this day would transport me from fragmented pieces to absolute dust.

“However, my story changed. Through a metamorphosis of inward self reflection and a malleability to forgive, 3 years did not stretch to forever. The gratitude of that truth has never lost its potency.

"I am magnetically transfixed by my mother, if you know me personally you know the magnitude of her presence in my life. (sic)"
