The diva of all divas Mariah Carey is joining “Empire” Season 3 and a recent trailer shows her at work in the studio. Fans are getting ready to see what the new installment of “Empire” has to offer when it returns in late September.

Mariah Carey on Empire Season 3

The “Touch My Body” singer will join the “Empire” cast as an ally to Cookie Lyon (Taraji P. Henson) despite what rumors say about the two women having beef with each other.

Henson told E! News that there is “no drama” between her character and Carey, while promoting her new film “Hidden Measures” at the Toronto International Film Festival. But knowing the Lyons, a friend today can easily become an enemy tomorrow, and then a friend again when they need you.

In the “Empire” promo, “Kill or be Killed,” Carey is in the studio with Cookie’s middle child, Jamal Lyon (Jussie Smollett). Are they recording a song together? Will Carey play herself or a character star like Alicia Keys’ Skye Summers in “Empire” Season 2?

“You always got a trick up your sleeve,” Carey tells Cookie in the promo. Maybe they are working together to revive her former record label The Lyon Dynasty.

The Lyons Are in Trouble

Meanwhile, it seems like the Lyons are going to get in another spat while Lucious Lyon (Terrence Howard) and Cookie’s past catches up to them. The two former drug dealers are now fighting an enemy who threatened to come after Cookie and her children.

“Just wait until I show him how dark hell can get,” Lucious says in the promo.

Who is he and what is he after? In Season 2, we learn that Cookie is hiding a big secret after Hakeem Lyon’s (Bryshere Y. Gray) ex-girlfriend told him of his mother’s dark past. But we still don’t know what the secret is. Maybe “Empire” Season 3 will reveal Cookie’s big secret.

Cookie and Lucious

Meanwhile, Cookie and Lucious are back to hating each other after he married frenemy Anika Calhoun (Grace Gealey) who is carrying his grandson from Hakeem.

“As long as I see that fire in your eyes, I know we’re still good,” Lucious told Cookie in the promo. But rumors say she is going to find a new lover in the upcoming season and completely move on from her ruthless ex-husband.

“Empire” returns to FOX on Wednesday Sept. 21. Stay tuned.
