Big Sean got extremely emotional during his The Tonight Show Starring Jimmy Fallon performance after breaking up with Ariana Grande! However, he was mostly getting teary-eyed because he dedicated the song “One Man Can Change The World” to his grandmother, who passed away in December.

“If anybody showed me one person can change the world, it’s her,” he said before his performance.

While he’s probably still reeling from his split with his girlfriend of eight months (which may have contributed to his tears), the track is about his family — and it is so touching.
