Jamie Adenuga (born 4 May 1985) from Hackney, London, better known by his stage name JME, is an English grime artist with African roots from Nigeria. He is the co-founder of the crew and label Boy Better Know. Adenuga was previously a part of the grime crew Meridian along with his brother, Joseph Adenuga (also known as Skepta.) As well as working with Boy Better Know, Adenuga now focuses mainly on his own solo ambitions. Unknown to many, the phrase "Boy Better Know" originated as a catchphrase from fellow Meridian Crew member and the founder of the label, Big H. JME has appeared on many grime DVDs including Practice Hours where Bossman, Big H and JME did a freestyle over the beat to his hit single 'Serious.'
