Jones confirmed the news on Twitter, writing, "I won't be hosting next seasons X Factor which is a shame but I can't complain as I've had a great time. Good luck to everyone on the show."

A Fox rep confirmed that Scherzinger also won't be back, according to the Hollywood Reporter.

An insider told E! the former Pussycat Doll wants to focus on her music career, adding, "She's spoken to Simon and he's given her his blessing."

Sources close to the show confirmed to Entertainment Weekly that Abdul also is parting ways with the Fox show.

"She found out today," a show source told E!. "At this point, the only ones staying are Simon and L.A. Reid."

"American Idol" executive producer Nigel Lythgoe chimed in on the reports, tweeting, "Shocked to see Simon has fired Paula Abdul, Nicole and Steve from the X-Factor."

Cowell debuted the American version of "The X Factor" last summer. So, why the sudden shakeup? There's no word for sure, but some reports speculate that ratings may play a role.

Cowell has previously said that his expectations for the show were too high. Prior to launching the series, Cowell had hoped to top "America Idol" viewership with 20 million weekly viewers, but "X Factor" ended with approximately 12.5 million viewers a week - behind both "Idol" and NBC's "The Voice."
