Demi Moore couldn’t be happier for her daughter Tallulah Willis following her engagement news.

Demi’s 27-year-old daughter and her ex-husband Bruce Willis recently announced that they will tie the knot with long-time partner Dillon Buss.

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

She posted a picture of herself getting a kiss on each cheek from Tallulah and Dillon, and wrote, “Congratulations to my little girl and adorable lover on their engagement! Happy day for the whole family “

Tallulah originally announced the news this week when she posted several snaps on her Instagram account with Dillon on one knee, writing, “Absolutely (sic)”

Then she posted a video showing her engagement ring and added, “STILL SHAKE HANDS – MOMS SPAGHETTI – I’m FIANCÉNCHED (sic)”

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

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

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

Scout wrote, “Crying, I’m so excited (sic)” while Rumer added, “I love these crazy kids. Congratulations @dillonbuss and @buuski, I love you both so much and I’m so excited for you

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

Tallulah and Demi were previously estranged for three years after Tallulah stopped speaking to her mother after the 58-year-old actress started drinking and using vicodin after breaking up with Ashton Kutcher in 2013.

And Tallulah previously said she felt like “absolute dust” during her alienation.

On Mother’s Day last year, she wrote on social media: “To give love and strength to every mother, tired mums, stepmothers and mothers who have lost something precious. I send it to everyone who has problems.” Celebrate a day that it reminds you of a loss.

“I haven’t spoken to my mother for almost 3 years and during that devastated time that day would transport me from fragmented pieces to absolute dust.

“However, my story has changed. To forgive through a metamorphosis of inner self-reflection and a malleability, 3 years did not extend forever. The gratitude of this truth has never lost its strength.

“I am magnetically banned from my mother. If you know me personally, you will know the extent of her presence in my life. (Sic)”
