The former Girls Aloud singer, who had been a judge on Britain's "X Factor" since 2008, was not included among the panel members announced by series producer Simon Cowell on Monday, according to the Hollywood Reporter.
Those who did make the cut: Destiny's Child singer Kelly Rowland, "Take That" singer-songwriter Gary Barlow, Tulisa Contostavlos of British hip-hop band N-Dubz, and boy-band impresario Louis Walsh.
"These four will be totally up for it, and each of them bring a different attitude," said Cowell.
Cole's departure from the show may have been her own doing. According to the Hollywood Reporter, she is said to have snubbed Cowell after she was reportedly fired from the U.S. series. Cole, who is believed to have been let go because her English accent is too thick for American audiences, has since been supposedly replaced on the Fox show by Pussycat Dolls singer Nicole Scherzinger. Simon Cowell, Paula Abdul and music producer L.A. Reid make up the remainder of the judges' panel.
The U.S. edition of "The X Factor" premieres in September, and auditions are already underway.
