London, UK (CNS) - X Factor judge Sharon Osbourne has verbally attacked co-judge Dannii Minogue.

Ozzy's wife says that Kylie's sister only landed the job because of her looks.

"She knows she's there because of her looks, not because of her contribution to the music industry," the 53-year-old music manager tells Graham Norton when she appeared on British TV Thursday night.

Osbourne also implies a potential romance between the pop star and another judge Simon Cowell.

"She's younger. She's better looking. Simon wants her and he doesn't want me. Thank God!"

X Factor is a British television music talent show co-produced by Cowell's production company. It is currently the biggest TV talent competition in Europe. Osbourne had been judge of the show since season 1 along with Cowell and Louis Walsh. Minogue joined the panel at the start of season 4.
