Riley Keough , whose mother, Lisa Marie Presley, died Jan. 12 after suffering a cardiac arrest, shared the last photo ever taken of them together on Tuesday. The heartfelt tribute came mere days after Keough hinted at the birth of her first child with husband Ben Smith-Petersen.

I feel blessed to have a photo of the last time I saw my beautiful mama, Keough captioned the Instagram post of her and Presley at a Jan. 8 event to celebrate Elvis Presleys birthday at West Hollywoods Formosa Caf. Grateful @georgieflores took this.

During a memorial service Sunday for Lisa Marie Presley at Graceland in Memphis, Tennessee, Smith-Petersen took the stage to read Keoughs words aloud, according to People . Keoughs tribute, which was read as she sat in the front row, also served as the unexpected announcement of a child.

Thank you for showing me love is the only thing that matters in this life, read Smith-Petersen. I hope I can love my daughter the way you loved me, the way you loved my brother and my sisters. Thank you for giving me strength, my heart. Im a product of your heart.
