Dannii Minogue has hit out at her fellow X Factor judge Simon Cowell, accusing him of dressing in boring clothes.

The Australian TV star even leveled the ultimate insult, saying that Louis Walsh is more stylish than Simon Cowell this year.

Speaking to The Sun, Minogue commented: “He’s letting the side down a bit. We just need him to ditch the boring trousers and T-shirts.

“It’s so much fun dressing up. I think it’s a really important part of the show – the contestants come along expecting a special day.”

She added: “Cheryl [Cole] and I both love to dress up and even Louis has made more of an effort this year. I like Simon’s style, though. He has this amazing power. He enjoys adulation and that’s great.”
