The actress described Benjamin as an "angel" and "pure light," and called him her "baby brother" and "best friend."
"Wild man. Intellectual. Witness to my life. Twin soul. Protector. Too sensitive for this harsh world," she continued.

"I can't believe you've left me. Not you sweet Ben Ben. Anyone but you. I guess this is true heartbreak. I hope we meet again," her emotional caption concluded.

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