Tallulah Willis felt like ''absolute dust'' amid her estrangement from her mother Demi Moore.

The 26-year-old actress has opened up about their turbulent relationship on Instagram, posting a candid message on the photo-sharing platform to mark Mother's Day on Sunday (10.05.20).

Tallulah - who didn't speak to Demi for three years, after she started drinking and using Vicodin following her split from Ashton Kutcher - wrote: ''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. I remember tearing up driving to work upon hearing a radio ad that cheerily recommend which 'perfume Mom would absolutely adore'. I digested the entire celebratory nature of the day as an insensitive slight to MY pain and MY story.

''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)''

Tallulah - whose father is actor Bruce Willis - subsequently admitted to learning valuable life lessons from the Hollywood actress.

She said: ''The here and now is a day that started with a running hug to my maternal deity and a sloppy cheek kiss. I revel in all that you are @demimoore and all that you continue to teach me. I witness what this day means for you, and where you came from. Every nook and cranny of you is worthy and gilded. I love you

''eternally your baby, tallulah belle (sic)''
