Sharon Stone is tearfully paying tribute to her late brother who just passed away this weekend … and it has her reflecting on the “tremendous loss” her family’s endured recently.

The actress confirmed Patrick‘s death, posting a video Monday evening with the caption “Godspeed Patrick Joseph Stone.” In the short clip, she says he did, in fact, suffer a fatal heart attack … and noted he’s the father of the late River Stone.

River was Patrick’s 11-month-old son who died in 2021 after his organs failed — and Sharon tearfully expresses how difficult these past couple years have been for her family.

SS says she’s thankful for all the love and support during this time, and appreciates the condolences she’s received as well … adding that the loss they’ve endured is just here on earth.

Remember, Sharon lost her grandmother and godmother in 2020 to COVID-19. As she copes with all that death, she’s encouraging people to continue being kind to one another.

TMZ broke the story … Patrick went into cardiac arrest Sunday in Pennsylvania, and for now — his death is being attributed to heart disease.

As Sharon pointed out, he’s survived by his wife and 2 children. Patrick was 57.
