Mariah Carey Steps into Iconic Jessica Rabbit Costume for Spooky Season: 'Happy Halloween!'

Mariah Carey is stepping into the shoes of another famous songstress for Halloween!

The singer, 54, dressed up as the iconic cartoon character Jessica Rabbit from Disney’s Who Framed Roger Rabbit on Instagram Monday — complete with a sparkly red dress and a bright red wig.

Carey shared a pair of photos of herself in the costume, which featured the character’s classic sultry red dress, purple elbow-length gloves and sparkly red stilettos — which Jessica famously wore while performing “Why Don’t You Do Right” in the classic 1988 movie

She also mimicked Jessica's signature poses and wore sparkly neutral eye makeup and bright red lipstick to complete the look.

“Happy Halloween! 🎃,” the “All I Want for Christmas Is You” singer captioned the post. She also wrote the hashtag “not yet” in a possible nod to the upcoming Christmas season. 

Earlier this month, the self-proclaimed “Queen of Christmas” showed she is already gearing up for the 2023 holiday season by starring in a new holiday campaign for The Children's Place alongside her 12-year-old twins, Moroccan and Monroe.

"The Children's Place is a household name, and it truly dominates the children's apparel space, so I've always been a fan of theirs," she exclusively explained to PEOPLE on Oct.17 about the collaboration. "Secondly, I'm just someone who absolutely loves the holidays. I mean, that's obvious, but I really do love holidays, specifically Christmas."

Carey added that she was excited to spend the holiday season with her son and daughter, but remained silent about their exact plans.

"I keep that part as secret as possible until we get everything set," she told PEOPLE. "It's just one of those things I do every year, where I make everybody wait to play Christmas music until I'm ready to take it in and feel like, 'OK, now it's time for the holidays.' "

Carey also said that she, Moroccan and Monroe "do the holiday season a little bit differently than most people," but noted, "We have a great time."

"We have our traditions, like rolling in the snow, jumping in the hot tubs — stuff that most people don't do, but it's just that we're all kind of daredevils," the Grammy Award winner shared.

"All of us spending time together is more than enough as a gift for what I want for Christmas, and what I want for my kids for Christmas is to just enjoy themselves, be happy, enjoy being with family, and feel loved," Carey added.
