JoJo Siwa’s over-the-top iHeartRadio Music Awards 2025 hair and makeup took 5 hours

Cindy Lou Who?

JoJo Siwa’s over-the-top glam at the 2025 iHeartRadio Music Awards was no easy feat.

The dancer-turned-musician walked the red carpet ahead of Monday night’s event in Los Angeles with half her face bejeweled and her hair styled in something that would make the beloved “Grinch” character shriek with pride.

Siwa explained to Page Six that her makeup — which featured rhinestones in the shape of an eye mask seemingly glued to her face — took about four hours to complete.

She said her long, brown hair — which was worn down and straight, with pieces of it woven into a massive shimmery pink-and-silver headpiece — “only took, like, an hour; it’s pretty chill.”

When we asked about the inspiration behind the look — which included a bedazzled Canadian tuxedo worn atop a pink Versace bra and underwear set — the 21-year-old admitted that it was her shocking ensemble from last year’s show.

“I was like, ‘Ah, s–t, I gotta top it,’” she confessed, adding, “I don’t think I did, but I think I got close, so I’ll take it.”

The “Dance Moms” star hard-launched her rebrand at the 2024 iHeartRadio Music Awards by sporting an out-of-character outfit comprised of a black-and-silver bodysuit with sheer and fishnet cutoutswhich she paired with combat boots.

She styled her blond locks in a faux-hawk, and she completed her “black beast look” with KISS-inspired face paint.

Siwa’s fans were stunned, as she’d always opted for child-friendly clothes and accessories.

“People are afraid of things they don’t know,” the “So You Think You Can Dance” judge told E! News on last year’s red carpet. “Things can be scary for people. New things can be very, very scary.”

Siwa added at the time that positive feedback from fellow artists like Lil Nas X and Meghan Trainor had encouraged her to lean into this new version of herself.

“The way that I’m able to keep going and keep being like, ‘Wait, actually, what I’m doing is right’ is because some of the most respected people in the world have come up to me and been like, ‘What you’re doing right now is so right. It is what the world needs, and I’m learning from what you are doing right now,’” she gushed.
