3M8S (pronounced Three mates) was a Flemish Belgian boyband in the early 2010s made up of Dean Delannoit, Kevin Kayirangwa and Dennis De Neyer, all former contestants on Belgian Idool.
The band was formed in May 2012 when the three members decided to join forces in a band with each one also continuing their solo careers whenever possible.
The name was chosen on the basis of a competition by the youth magazine JOEPIE.
The band has been relatively successful and took part in the preliminary rounds for preliminary rounds of "Eurosong 2014" to try to represent Belgium in 2014 Eurovision Song Contest, and was eliminated in the early rounds of the selection.
Later the boy band announced that it would stop so that members would focus on their solo career.
