These portraits look just like photographs - but they were actually drawn in pencil!
Artist Kelvin Okafor has won awards for his drawings which have been described as 'photo realistic' because they look so lifelike.
Each one takes about 100 hours to draw.
Could you tell the difference between his Bieber drawing and a real photograph?
