According to MTV, Katy Perry has been approached to become a judge on the US version of The X Factor, the show for which Simon Cowell left American Idol. Reports say that Perry has been offered $340,000 a week to do the gig.

A source says that Simon Cowell has very specific ideas about who he wants on the panel: “At least one massive American star, someone who is known globally, plus one Brit and at least one authoritative male.”

Rumor has it that Nicole Scherzinger and Cheryl Cole are also on the short list of possible X Factor judges.
