Obsessed is an understatement. 

Mariah Carey channeled her inner Sandy from “Grease” in a head-to-toe black leather outfit on Monday night. 

The songstress, 54, stepped out in the edgy ensemble to hit the afterparty for Joaquin Phoenix’s new movie, “Beau Is Afraid.”

Carey’s all-black outfit included a Prada tank top ($995), a cropped moto jacket and skintight Mugler leggings.

She finished her look with towering Louis Vuitton platform sandals, oversized sunglasses, a braided belt and glamorous statement earrings.

The “Glitter” star even toted a lollipop (the ultimate accessory) in some snaps.

Carey wore her hair in long, loose curls and kept her makeup minimal with a rosy pout.

Fans loved the pictures, with one person on Twitter calling her “so extra.” 

Carey always goes for over-the-top glamour, whether she’s soaking in a hot tub wearing a sequined Tom Ford gown or lounging in a six-figure Prada sweatsuit.

The Christmas queen has been busy this spring.

Over the weekend, Carey celebrated Easter with her 11-year-old twins, Monroe and Moroccan, joined by baby bunnies. 

The twins also appear to have celebrated the holiday with their dad, Nick Cannon, and a few of their siblings.

Cannon – who welcomed his 12th child in December – still adores ex Carey.

The “Wild ‘n Out” presenter called the diva “the love of his life” earlier this month.
