The 'Lights Out' singer has paid tribute to her late son, who passed away from a self-inflicted gunshot wound in July, admitting she "will never be the same" after his tragic passing.

She wrote on Instagram: "My beautiful beautiful angel, I worshipped the ground you walked on, on this earth and now in Heaven. My heart and soul went with you. The depth of the pain is suffocating and bottomless without you every moment of every day. I will never be the same. Please wait for me my love, and hold my hand while I stay to continue to protect and raise your little sisters and to be here for Riley. I know you would want that. Happy Birthday my sweet sweet Boy. You were much too good for this world. (sic)"

Benjamin was laid to rest next to his grandfather Elvis Presley.

Elvis Presley's Graceland said in a statement: "Benjamin Storm Keough was laid to rest in the Meditation Garden at Graceland with his family including his grandfather, Elvis Presley, great-grandmother, Gladys Presley, great-grandfather, Vernon Presley and great-great-grandmother, Minnie Mae Presley."

When Benjamin passed away, his mother Lisa Marie Presley admitted she has been left "completely heartbroken" by the death of her son.

A spokesperson for Lisa Marie - who also has daughter Riley with Danny and 11-year-old twins Finley and Harper with her fourth husband Michael Lockwood - said: "She is completely heartbroken, inconsolable and beyond devastated but trying to stay strong for her 11 year old twins and her oldest daughter Riley. She adored that boy. He was the love of her life."

Benjamin was known for his strong resemblance to his late grandfather, Elvis Presley, which his mother has admitted left fans shocked.

She previously said: "Ben does look so much like Elvis. He was at the Opry and was the quiet storm behind the stage. Everybody turned around and looked when he was over there. Everybody was grabbing him for a photo because it is just uncanny."
