Yes, you read correctly. There is supposedly an upcoming 21 member boy band called Double B 21.

I thought the 6th grade girl group member was ridiculous, but this might be just as bad. In this music video of their song One, you can only spot seven members, but that's due to them splitting it up into three groups of seven to perform, because 21 is just too many for one stage. I'm not 100% sure as to how they're going to work this out - but it's sure going to be interesting and a major headache memorizing each member of the group. At least the song is not a cheesy dance track, but rather a soothing ballad that is nice to listen to. Check it out: http://www.youtube.com/watch?v=GHcp8BEOy5A
