Kendrick Lamar isn't the biggest guy: he's listed at 5'5.
He's down in Australia, and he must be worried about ill-tempered kangaroos because he has a bodyguard who appears to be a full 50 percent bigger than he is.
The large man in the TDE hoodie is probably not eight feet tall. So his massive size is somewhat of a function of the camera angle.
Kendrick and his huge buddy have been in Australia and New Zealand for the last couple of weeks, playing shows and the Splendour in the Grass festival.
