The sparkling eyes of this Irish leprechaun hide a heart of stone. Always with the focus on the money, Walsh managed the early careers of Boyzone and Girls Aloud but has managed to fall out with them following some indiscreet comments and decisions which treated the 'artists' more like 'products'.

It's scary to know that people like Louis control pop. Has never married.
