Pop star Mika has signed up as a judge on the Italian version of hit reality show The X Factor.

The Grace Kelly hitmaker previously guest judged on an episode of the talent series, and now he has signed a deal to make the role permanent.

Editors at Repubblica.it quote Mika as saying, "I'm taking Italian lessons, not only in terms of language, but also of (sic) music."

Britney Spears, Demi Lovato, Nicole Scherzinger and Gary Barlow are among the big name singing stars who have served as judges on other versions of the show.
