Bad Boy band of brothers B5 -- short for Breeding 5, à la the Jackson 5 -- began as TNT Boyz but changed the name when youngest sibling Bryan joined up. Carnell, Dustin, Kelly, and Patrick won a number of talent competitions during the late '90s and early 2000s, developing their energetic performance style while gaining attention from a number of industry heavyweights. 

P. Diddy eventually took the group under his wings, signing them to Bad Boy and arranging a roster of reputable producers to collaborate with them for their debut album.
