The X Factor‘s Louis Walsh has lashed out at his fellow judges and said that he missed Sharon Osbourne’s feisty outbursts.

The 56-year-old Westlife manager has branded Simon arrogant and mocked Dannii’s appearance, according to The Sun.

Louis – who now only has act JLS remaining in the competition after Bad Lashes and Girlband were voted off the show – also claimed Simon, 49, and Dannii, 37, were barely speaking to each other.

Louis said: “Simon thinks it’s his world. It’s his world and we are all lucky to live in it. He is pompous, and he’s arrogant and successful.”

Louis also passed comment on Dannii’s looks, who has admitted having Botox. He said: “I remember buying her album years ago. She looks totally different now!”

Commenting on rumours of a feud between Dannii and Simon, he added: “Dannii and Simon are talking, just not much.”

Only Girls Aloud’s Cheryl Cole, 25, escaped Louis’ rant in an interview on The Paul O’Grady Show, which screened on Channel 4 on Thursday.

Louis revealed he missed former judge Sharon Osbourne, 56, who quit the series earlier this year. “Simon couldn’t control Sharon. She’s a loose cannon, didn’t care about him, said what she wanted and I loved that.”
