Carey plays a singer named Kitty, who joins Jamal (Jussie Smollett) in the recording studio to record a sultry duet. The clip also shows Kitty's first interaction with Cookie (Taraji P. Henson) and introduces the return of Shine (Xzibit) and Lucious' half-brother, Tariq (Morocco Omari).
ET was with Carey recently, where she teased the tune she’s been working on for her Empire guest turn.
"I was in the studio last night and one of the things I had to do was get a song together," Carey said, adding that Kitty will be "pretty glamorous."
Smollett also revealed to ET that Carey vocally produced the recording.
"It was incredible!" Smollett said. "She landed at 1 a.m. She came into the studio. We were there until seven in the morning, and we just recorded the song, and it was incredible, and I love her. It's different getting to know someone that you love and respect and being able to work and do the work with that someone."
