Post Malone Sends Surprise Video Honoring Late Staten Island, NY, Principal

Post Malone did a good deed — a very good deed — for students who were grieving over the death of their principal.

Post recorded a video for students at P.S. 56, The Louis Desario School in Staten Island. Principal, Phil Carollo, died suddenly last month at 49 … apparently from a heart attack.

Phil’s widow Erin tells TMZ … her husband was a huge Post Malone fan … the fam would take car rides and all they played was PM as the couple and their kids sang along.

Well, Phil would have celebrated his 50th birthday Friday, so folks at the school wanted to do something special. They held a carnival, and wanted Post to record a vid honoring Phil that could be played to all the students.

One of the teachers, Linda Acevado, started an online petition to get Post to record the video. She says she emailed the petition to Post’s agents, manager, business partners and recordbut got no response.

Linda was undeterred … a colleague had a friend who somehow had a way to get to Post, and he recorded the video.

You see Linda in the video break down in tears as an emotional Post offers words of comfort to the students.
