Riley Keough gets tattoo in honor of late brother Benjamin Keough, Elvis Presley's grandson

Actress Riley Keough, the eldest grandchild of Elvis Presley, is sharing how she's memorializing her little brother Benjamin Keough, who died earlier this month.

Benjamin, the son of actress Lisa Marie Presley and the lookalike grandson of Elvis, died by suicide at 27 on July 12. Benjamin's father is singer-songwriter Danny Keough.

In an Instagram story Tuesday, Riley, 31, shared a photo of her new ink: his name in cursive above her collarbone: "Benjamin Storm." In the post, she also added a heart emoji.

Before and after the tattoo post, Riley also shared old videos of Benjamin. In one, the pair and actor Shusaku Kakizawa (who Riley tagged) laughed about a "rogue cheeseburger" being left in their hotel room.

Kakizawa shared the clip to his Instagram as well with a message.

"Ben, I don't know how you still manage to make me laugh so hard. I miss you so much.." he wrote.

In a following clip, Benjamin says, "we're walking up some very tall stairs to go see some –" and then he turns the camera to Riley, who finishes the sentence: "Monkeys!"

The final video is of Benjamin recording himself and the view behind him.

"Hey Ri, just hanging out on top of a mountain in Kyoto," he says in the short clip.

On July 18, Riley posted an emotional tribute to her brother.

"Mornings are the hardest, I forget you're gone," she began.

Breaking her silence on the death, Riley dedicated the post to her "baby brother" with a series of photos of the two laughing in happier times.

"I can’t cry because of the fear that I will never stop. A pain that’s new to me," Riley wrote. "There are no words for you. Angel is the closest I could think of. Pure light. Baby brother. Best friend. Wild man. Intellectual. Witness to my life. Twin soul. Protector. Too sensitive for this harsh world."
