If you were locked in an interrogation room with Iron Man's best mate Don Cheadle, you'd think you were screwed, right? Not if you're Kendrick Lamar.

In the rapper's latest music video,Lamaris handcuffed and hooked up to a lie detector, while a mean looking Cheadlebaits him ahead of the test:"Kendrick Lamar. Two first names, huh? The f**k is up with that?"

As Cheadle hits the ‘on’ switch though, hesuddenly becomes possessed by the spirit of Lamar and lip syncs the hell out of the track. 'Watch it below (warning explicit lyrics):'

If Don doesn't perform that on 'Lip Sync Battle' soon it'll be a travesty of a missedopportunity.

‘DNA.’ is the latest video to drop from Kendrick’s brand new album 'DAMN.'which is currently battling with Ed Sheeran’s ÷ for No.1 on the Official UK Albums Chart this Friday.
