JLS' Marvin Humes has turned his ordeal at the hands of school bullies into a positive thing, by becoming involved with the charity Childline. In this new video, the JLS singer visits a school to talk to the kids about his experiences - and does a spot of pretty impressive singing to a whole assembly hall full of children. The man deserves a bravery award for that alone. If you're a JLS fan, this will make you fall even more in love with Mr Humes, and if you're not? Well, this might just win you over.
