Justin Bieber starting playing the drums at age 2. Justin got his first drum set at age 4. Justin has been playing the drums since.
Justin also plays guitar. When he got his first guitar he self taught himself how to play.
Justin sometimes will play these instruments during his concerts. So if you ever want to see him play one or both of the instruments buy tickets and go to one of his concerts, OR just go to youtube and type Justin Bieber playing drums (or guitar).
