Tallulah originally shared several snaps to her Instagram account which featured Dillon on one knee, and wrote: “with absolute most certainty (sic)”

Meanwhile, Tallulah admitted last year she felt like "absolute dust"

amid her estrangement from her mother Demi Moore, whom she didn’t speak to for three years, after Demi started drinking and using Vicodin following her split from Ashton Kutcher in 2013.

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)"
