Hilary Duff has been accused of undergoing plastic or cosmetic surgery ahead of her return to music.

The former Disney star, now 38, is currently working on a new pop album, but fans have noticed that she’s looking surprisingly ageless ahead of her big comeback.

During an appearance at the Fendi show at Milan Fashion Week last month, Duff looked like she’d barely aged a day since her time as a teen pop idol.

The outing came just several months after the actress sparked speculation that she’d experimented with injectables after stepping out in Los Angeles with noticeably fuller cheeks.

Social media has had a field day with Duff’s changing looks, with beauty influencer Dana Omari suggesting that the Fly singer has undergone multiple procedures over the years.

‘At first glance, nose job, brow lift, probably faceliftcheek aug, lip filler, BotoxDysport etc,’ she wrote on her popular account, IG Famous by Dana.

Nurse Melanie Jane on TikTok said that Duff had ‘aged so gracefully,’ but stated that she may have possibly had Botox and lip filler.

Speaking to the Daily Mail, board-certified plastic surgeon Dr. Yael Halaas, who has not treated Duff, believes that the Lizzie McGuire star may have dabbled in injectables over the years, but is not convinced that she’s had any major plastic surgery.

‘I don’t think Hilary Duff has had much changes to her face but she does look like she had filler to her cheeks,’ Dr. Halaas said.

‘Upon looking at her side profile, it’s my opinion that there is an excess of volume that gives her that C-shape under the eyes, along to the sides of the upper side of her cheek,’ she continued.

‘Often it can look overdone when it’s first injected, but once it settles, what we usually see is a younger lifted face.’

She added, ‘If done right, it can appear to look natural, making people wonder what was really done. She’s a perfect example of this.’

Duff herself has never publicly commented on whether or not she’s had any work done.

Earlier this year, Duff’s husband Matthew Koma clapped back at comments suggesting that she had gotten cheek filler and Botox.

It all started when Duff posted a series of closeups of herself in a canary-yellow sweater dress that emphasized her smooth skin and prominent cheekbones.

Most of the post’s comments fawned over the Lizzie McGuire star and her vibrant look, but her husband zoomed in on one of the rare negative comments after it accused his wife of using Botox to achieve her youthful visage.

‘Why did she do Botox, I swear to god everyone else is the same,’ the commenter wrote, though Hilary has never confirmed that she has used Botox.

‘Get f***ed butterfly,’ Matthew shot back, referencing the original commenter’s username while significantly escalating the situation.

The mom-of-four’s new look comes as she’s preparing to return to the music scene after a decade.

Duff hasn’t released a new album since 2015’s Breathe In, Breathe Out, but the former hitmaker recently signed with Atlantic Records and is working on new music.

In addition to another album, the Younger star is also preparing a documentary series with concert director Sam Welch about her return to music after ten years.

Welch has been behind some of the biggest pop star films in recent memory, including Taylor Swift’s The Eras Tour and BTS: Permission to Dance on Stage – LA.

In a 2022 cover story for Women’s Health, Duff explained that she wanted to prioritize her mental health in the same way that she thought many women focus on their appearance.

‘We bust our a** to get our bodies in shape and to look the best we can. We get facials and Botox and our hair done and highlights and brows and lash lifts and all this s***. But I want to work on the inside,’ she said.

‘That’s the most important part of the system,’ she added.
