Katy Perry to be American X Factor judge?

Chart-topper Katy Perry could become a permanent judge on the US version of Simon Cowell’s TV show The X Factor.

The California Gurls performer – who is also currently in talks for her own British TV series – recently appeared as a guest judge on the UK version of the show.

And Cowell was so impressed, that he now wants the 25-year-old to join him on the panel when the contest launches next year.

“Simon wants to get the judging names signed, sealed and announced within six weeks,” an insider close to the singer revealed to British tabloid the Mirror.

“He wants at least one massive American star, someone who is known globally, plus one Brit and at least one authoritative male. Katy was thrilled, especially by the package which is said to be a $340,000-a-show deal.”

The insider revealed further: “Jennifer Lopez was a serious consideration as was her husband Marc Anthony. Mariah Carey’s other half, Nick Cannon, is also in the frame. But Katy really came on Simon’s radar after the Dublin auditions. She absolutely nailed it. She was a natural.”

It’s also believed Nicole Scherzinger could be joining the show as a judge.
