The actress uploaded a selfie in which she had tears rolling down her cheeks and a forlorn expression.
She simply captioned it: "Pisces saying goodbye to anyone." The unhappy image came days after Kevin paid a touching tribute on social media following the death of his good friend, actor Fred Ward.

He posted a photo of the pair of them in character in the film Tremors, alongside a touching message which read: "So sad to hear about Fred Ward. When it came to battling underground worms I couldn’t have asked for a better partner.
"I will always remember chatting about his love of Django Reinhardt and jazz guitar during our long, hot days in the high desert. Rest In Peace Fred."
Sosie didn't reveal whether her sadness was for the loss of Fred, but it's likely the star knew her father's friend too.

A statement to the New York Post by the actor's representatives said that he died on 8 May."I am sad to announce the passing of acclaimed actor Fred Ward, who passed away on Sunday, May 8, 2022, at age 79," the statement read.
