FOX officially announced the singer as one of its new judges.
Mariah Carey is known for her diva demands — she once insisted “I don’t do stairs” — but who knew she has a wicked sense of humor, too?

The 42-year-old songstress is set to give American Idol a new lease on life, but according to her brother, the mother of two will bring a lot more than that to the ailing FOX show.

“Mariah is hysterically funny, and I don’t think people really know that,” the songstress’ sibling, Morgan Carey, told Celebuzz.

“I think her fans and fans of the show will appreciate her sense of humor. She’s classic.”

Carey’s new role was announced on July 23 when she signed a reported $18 million deal to replace Jennifer Lopez, who said she was leaving the show to pursue other projects.

But Carey’s brother said he think his sister’s arrival to the show could not have come sooner.

“I think it’s going to be wonderful to have such a high level of artistry on the show… finally,” Morgan added.

According to the singer’s husband Nick Cannon, the “Obsessed” singer will be a tough judge on American Idol and not let mediocre talent hit the stage.

“She’s very serious about music and singing. She’ll probably be the toughest judge that’s ever been on [the] show,” Cannon told Access Hollywood.
