And just to turn the skeptics into true Beliebers about the authenticity of his work, the singer posted another video, writing, "For the people who think I picked the paint brush to look like I am painting I'm really in this sh*t."

Then, knowing the world would not truly be at peace with just two videos of Justin painting, the 21-year-old uploaded a third, writing, "Work hard play hard."

Meanwhile, it's just been good deeds all around for Justin recently, who gave family friend Kourtney Kardashian a lift home last Friday after a fun night out.

An eyewitness tells ET that the two arrived separately to a West Hollywood, California haunt, they left together through the back door and hopped into Justin's black Escalade, and headed to Universal Studios Hollywood Horror Nights, where they hit up the This Is The End 3D maze.
