Stone also shared a photo of her and Patrick together in a separate Instagram post.

Fellow celebrities took to the comments section to send their condolences to Stone and her family.

"Dearest Sharon, I'm so sorry for your loss. I do understand very well what you're going through. With love," actor John Travolta wrote.

Singer Gloria Estefan commented, "Sending love and prayers to accompany you and your family throughout this incredibly difficult time of grief & loss."

Patrick is survived by his wife Tasha and their children Kaylee and Hunter.
