Nikki Glaser shared shocking throwback photos of herself after revealing her plans to undergo major plastic surgery.

The comedian took to Instagram Wednesday to post a side-by-side collage of herself on “The Tonight Show” in January 2009 and her most recent appearance on Monday.

Glaser appeared nearly unrecognizable in the photo taken 16 years ago when she was 24 years old and getting her start in the entertainment industry.

The actress, now 40, wore a black strapless dress, black sweater and black boots for the first time on the late-night show with then-host Jay Leno. She styled her medium-length hair with a side part.

Glaser, meanwhile, stepped out sporting a black suit on Monday night’s episode of the show with host Jimmy Fallon. She wore her blond locks with a middle part.

The TV personality also changed into a mini silver dress and stilletos.

Several fans gushed over Glaser’s glowup, with one writing, “ummmm I’ll have what’s she’s having ✨✨✨😍.”

“Love this evolution!’ 🙌🏻 I truly feel like the more I age, the more I feel comfortable in my own skin. You’re radiating and it shows! ✨,” another gushed.

“Love this journey for you” a third added.

While on “The Tonight Show” Monday, Glaser told Fallon that she planned on going under the knife next year.

“Wait till the facelift,” she quipped. “That’s coming. August 2026. I’m gonna do it. I have no problem with that.”

“You’ve got to do it subtly, so they go, ‘What’s she doing?’ and you can just go, ‘Just meditating more,” Glaser continued.

“I’m doing the type of meditation that removes your eyelid skin.’ That’s what they say, ‘I’m drinking more water. I’m just working on my gut health, so my brow has been lowered two inches,’” she added.

Glaser described the procedure as “a wise investment,” saying, “People treat you better when you’re hotter. It’s just a fact. It’s a sad fact of life.”

In December, Glaser also admitted that she postponed having a brow lift to host the 2025 Golden Globes.
