VIDEO : Vin Diesel Performs Heartbreaking Song in Memory of Paul Walker

There's nothing Vin Diesel loves more than karaoke and Paul Walker.
The Furious 7 actor has been publicly grieving for his castmate Walker since he died in a car crash in November 2013, making endless tributes to him during interviews and even naming his daughter Pauline.
And being an avid singer and karaoke star, he has recently taken to the stage to perform Tove Lo's "Habits," hoping the music would help the "process of healing." As Vin Diesel performed, a montage, titled "Brotherhood," flashed on the screen behind him, featuring clips of he and Walker from many Fast and Furious sets. It's heartbreaking, moving and personal.??
