Watch: 'SNL' Goes After Jojo Siwa's 'Mature' Persona with Weekend Update Segment

In March, child star Jojo Siwa promised fans that she was about to unleash material that was "not made for children." But when she debuted her mature persona, "SNL" found it ripe for comedy.

The long-running sketch comedy show went after Siwa's new "mature" vibe on its May 4 episode, when "Chloe Fineman appeared as Siwa at the Weekend Update desk dressed in head-to-toe black glitter and a black body suit, the same outfit from Siwa's music video for her new single 'Karma'," Variety reported.

Siwa's wardrobe in the video was accompanied by a makeup job that looked like something from the 1970s heyday of the glam rock band Kiss; that makeup job was also part of Fineman's depiction.

Fineman as Siwa exclaimed to anchor Colin Jost, "That's right, Colin; I'm a bad girl now!"

"This is a very different look," Jost said. "We're all used to you wearing outfits like this," he added, as a photo of Siwa wearing pigtails, a cute, brightly-colored outfit, and a lime-green bow in her hair appeared onscreen.

"It's a pretty big change," Jost noted.

Agreed Fineman: "It's a pretty big change. I used to be way more sparkles, and now I'm black sparkles."

Fineman went on to voice thoughts that some may have had since Siwa debuted her new style.

"I look like if a figure skater joined a street gang," Fineman declared.

"Yeah, I was gonna say, 'If Mad Max was on Broadway," Jot rejoined.

Fineman went on to menace Jost with: "Does a former child star looking like this scare you?"

"Yeah," Jost jibed in reply. "But not in the way you're hoping!"

Siwa came out three years ago, but Fineman used that as further evidence of the onetime "Dance Moms" star's maturation.

"I'm 20 and I'm gay!" Fineman exclaimed, Variety detailed. "I'm the first gay girl in the world! Bet you never met a gay girl before!"

Drolly, Jost snarked: "As a matter of fact, a lot of the women I dated turned gay." Then he turned on the heat, bringing up a recent flap in which Siwa exasperated any number of out LGBTQ+ musicians in an interview when she announced she wanted to create a whole new musical genre she thought she'd call "gay pop."

"That's maybe just pop," Jost suggested.

In real life, Siwa was quick to acknowledge that the "new" genre already existed, and had been pioneered by LGBTQ+ musicians who came well before her.

"I definitely am not the inventor of gay pop, for sure not," Siwa told TMZ during the ensuing backlash. "But I do want to be a piece in making it bigger than it already is. I want to bring more attention to it."

Mission accomplished, though perhaps not quite in the way Siwa intended. As for her "maturation"... there's still time.
