Five days after telling TCA her experience on Fox’s series American Idol was “the most abusive” ever, Fox announced Carey is returning to the network to guest star on Empire.

Empire hails from Imagine Television in association with 20th Century Fox Television, was created by Lee Daniels and Danny Strong, and executive-produced by Daniels, Strong, Brian Grazer, Ilene Chaiken, Francie Calfo and Sanaa Hamri.

American Idol did not.

In return for agreeing to grace Empire, Fox called her “Global Icon Mariah Carey” in its announcement, and noted she is the “best-selling female recording artist of all time.” Carey will play Kitty, a “mega-superstar who comes to Empire to collaborate with Jamal Lyon (Jussie Smollett) on an explosive new song.” When the duet encounters obstacles, Kitty “helps Jamal dig deep to overcome personal difficulties and reach a musical breakthrough.”

Carey guests on October 5, joining previously announced Empire guest stars Taye Diggs, Sierra McClain, French Montana and Birdman. Empire returns September 21.

Not coincidentally, Carey is about to begin the second half of her Las Vegas residency, “Mariah #1 to Infinity,” at Caesars Palace later this month. She then heads to Latin America this fall with her “Sweet Sweet Fantasy” tour of Argentina, Chile, Brazil and Mexico.

Five days ago, Carey stopped by TCA to talk about her upcoming E! docuseries Mariah’s World, her Sweet Sweet Fantasy concert tour and her personal life. Only one TV critic insisted on dragging the conversation back to her one season as judge on Fox’s singing competition series, three years back. The mere mention of Idol set Carey off. “Ugh! It was the most the most abusive experience!” she groaned. “By the way, you’ve just driven me to drink,” she scolded the reporter, stopping the interview to have a “splash” of Veuve Clicquot. “I need a festive moment,” she said as she “splashed,” anxious E! execs waited, and reporters tweeted.
