Do you know who Lamar's biggest fan is? See how well you know the 'Good Kid' rapper.
Seriously, you need to see him doing 50 Cent's 'Candy Shop'.
We never thought we'd say this, but it turns out Kendrick Lamar is a massive fan of karaoke.
On a recent visit to the XXL offices, he found himself locked in a room with a karaoke machine and fortunately a video captured the moment K-Dot tackled some classic songs including 50 Cent's 'Candy Shop', as well as tracks by Eminem and Jay Z.
