Celebrity Big Brother's Louis Walsh had a surprising one-liner when asked about the worst thing he's ever done as the house transformed into a twisted fairytale kingdom and Louise was positioned as the most evil housemate. After surviving a tough double eviction last week, Louis was asked about his most wicked deed. Without missing a beat, he confessed it was "inflicting a lot of bad pop songs on the public".The former music manager and X Factor judge has had a few clashes with his past stars, from calling Jedward "vile" to labelling Ronan Keating a "wannabe who had to be stopped".
