Lisa Marie Presley Posts Touching Tribute To Late Son Benjamin Keough On His Birthday

Lisa Marie Presley shared a heartbreaking message for her late son Benjamin Keough on what would have been his 28th birthday.

Paying tribute to Benjamin, who died by suicide on July 12, Presley shared a photo of him from a previous birthday celebration and wrote that every day without him was "suffocating."

"My beautiful beautiful angel, I worshipped the ground you walked on, on this earth and now in Heaven," Presley wrote on Instagram Wednesday. "My heart and soul went with you."

"The depth of the pain is suffocating and bottomless without you every moment of every day," she continued. “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."

Presley is also mother to 31-year-old daughter Riley, an actress, and 11-year-old twin daughters, Harper and Finley.

Riley also took to social media Wednesday to honor her late brother with a slideshow on Instagram that included pictures from their childhood as well as from her wedding to stuntman Ben Smith-Peterson in 2015.

"Happy Birthday beautiful angel," Riley captioned the post.

Another person who remembered Benjamin on what would have been his 28th birthday was his former girlfriend, Diana Pinto, who posted several photos of herself with Benjamin on Instagram.

Benjamin died on July 12 at his home in Calabasas, California, following a self-inflicted gunshot wound. The Los Angeles County Medical Examiner’s Office ruled his death as a suicide.

Shortly after Benjamin’s death, his friend, musician Brandon Howard, told People that the pressure of bearing the Presley family name was "definitely a part of what happened."

Benjamin also struggled with depression, Howard said.

"It's a tough thing when you have a lot of pressure with your family and living up to a name and an image," Howard said. "It's a lot of pressure. It's almost like you're pressured into having to be a musician, having to be an actor. It was good for him to go around the world and discover himself and have his own friends. You never know what triggers it. You never know ... It's so random."
