Benjamin Keough's ex-girlfriend remembers her ‘favorite person’ after death

He was the son of Lisa Marie Presley and Elvis Presley’s grandson

Benjamin Keough’s ex-girlfriend Alexa Rhode wrote a touching tribute to the late son of Lisa Marie Presley following his death on Sunday.

Rhode posted photos of Keough in the pool, fishing, eating sushi, at his birthday, and goofy moments between the two.

“Benjamin Storm, YOU. Always happy in the sun and water. And a laugh that made everyone happier. You gave love to anyone who needed it. You were wise like a thousand year old man, but silly as a 5 year old,” she wrote.

Rhode continued: “You always said your favorite tarot card was the hermit, cause you could relate. You made the best jokes, and always broke the rules.”

“You were my favorite person from the moment I met you,” Keough’s ex-girlfriend expressed. “I wish we could’ve kept you forever Ben Ben.”

Rhode ended her message, “I hope you’re having all the delicious sushi in paradise. Words will never be enough.”
