It is the sixth single from their debut album Uncle B and was produced by Kano and Fraser T Smith.

David Balls of Digital Spy wrote: "If the frequency with which their Uncle B album ad gets repeated on TV is in any way indicative of the band's popularity, N-Dubz have a very promising future ahead of them.

After a spluttering start that saw them win a MOBO, then get dropped and signed again, Tulisa, Fazer and Dappy have conquered the airwaves of late and are now aiming for a fourth consecutive top 30 hit.

'Strong Again' is another urban/pop crossover track that sounds like The Black Eyed Peas just bumped into Dizzee Rascal and got on like a house on fire.

With tidier production than their earlier singles, this manages to sound accessible and radio-friendly without sacrificing its all-important street cred.
