### Instruction: Who are N-Dubz?
### Response: N-Dubz are a popular band in the United Kingdom, made up of Tulisa, Fazer, and Dappy, formed out of London. The band were formed when they were young teenagers in the early 2000s. They were inspired to form the band by Dappy's late father, known to the band as "Uncle B". Their song "Papa can you hear me?" is a tribute to Uncle B. Tulisa and Dappy are cousins, whilst Fazer has always been a close friend.
The trio have had many successful hits, and collaborated with popular artists like Tinchy Strider and Skepta. They parted ways in 2011, and Dappy started a solo career, whilst Tulisa became a judge on the popular UK show "The X Factor". She formed and mentored the winning band Little Mix. 
The band reunited in 2022 and released new music, along with a sold out UK tour.
