A chart-topping pop legend made a bold return to daytime television, but it wasn’t her voice that had the internet buzzing. It was all about her surprising looks.

Christina Aguilera, 44, stunned fans and critics alike with her dramatic appearance on the December 9, 2025, episode of "The Jennifer Hudson Show" in Burbank.

While the "Genie in a Bottle" singer came to talk about several topics, like motherhood, viewers found themselves discussing something else entirely: her unexpected resemblance to a 26-year-old rising star.

As she arrived at the studio, Aguilera commanded attention in a sheer, nude-toned, high-necked organza dress thatclung to her body in all the right places.

Underneath was a beige piece with a red pattern, mimicking the look of a bikini top and shorts, with a red mark near the belly button that instantly drew the eye.

She completed the look with thigh-high red velvet boots, finished in a pointed toe heel. But it was her platinum blonde hair, parted to the side and styled in soft vintage waves, that truly set the tone.

Paired with her confidence and glow, Aguilera looked noticeably youthful, so much so that it left fans doing double takes.

"I love her but her face changing so much just weirds me out. Like it’s her voice but not the face I grew up with," one Redditor shared. "Too much plastic surgery," another bluntly stated.

While some fans agreed and others disagreed, insisting she looked incredible, the conversation around her changing appearance refused to die down. And it later evolved into something entirely unexpected.

An Interesting Comparison

Amid all the critiques, one surprising observation emerged. It wasn’t about her outfit, her hair, or even about beauty treatments. People felt like they were looking atsomeone else.

Christina Aguilera, known for reinventing herself over the years, had fans saying she looked like a pop star nearly half her age, whose work has topped the charts consistently since her breakout hit "Espresso."

One Redditor simply wrote, "She looks like Sabrina Carpenter." Another echoed the same on Instagram, "Looks exactly like Sabrina Carpenter."

And this isn’t the first time she has shocked netizens this year. She attended the official photocall for "Burlesque the Musical," which she executive produced, at The Savoy Theatre in London, England, on July 21.

Her appearance had many online wondering who they were looking at.

A Musical Outfit

For the appearance, Aguilera wore a sultry olive green corset-style dress that featured bold criss-cross ribbon detailing along the front, tightly drawing in the fabric from her bust down to her waist and hips.

The dress included a jagged, layered hemline that brought a sense of edgy movement to the ensemble. Her mid-length platinum blonde hair was worn pin-straight and parted cleanly down the middle.

She paired the look with sleek black knee-high leather boots and added a touch of shine with stacked silver rings. Her makeup was unapologetically bold, with dark berry lipstick, sharply defined brows, and sculpted cheeks that amplified the drama of her overall presentation.

Social media reactions to Aguilera’s daring ensemble were mixed and fiercely debated across multiple platforms. On Facebook, one person commented, "ozempic face. smh. sunken eyes. no collagen. ugh. WHY [sic]?!"

Completely Changed at Award’s Ceremony

While the event celebrated achievements in science and mathematics, much of the spotlight was instantly **hijacked **by the Grammy-winning singer, whose jaw-dropping red-carpet look ignited a flurry of online buzz.

Dressed in a flowing white gown with dramatic, high-impact styling, Aguilera stopped the show the moment she stepped onto the carpet. The sheer, floor-length dress featured a corset-style bodice laced tightly at the front and cinched at the waist, injecting bold structure into the billowing, ethereal fabric that floated around her like a vision.

A cape cascading from each shoulder amplified the ensemble’s goddess-like aura, while a daring deep V neckline plunged low, framed by glimmering diamond jewelry that caught the light with every step.

Her signature platinum-blonde hair was styled in long, beachy waves, with a tight braid pulled into a high half-up ponytail for added drama. Her makeup was equally striking, with bold lashes, sharply defined brows, and a swipe of deep rose lipstick completing the powerful look.

Another observed, "She’s had so many surgeries and face changes. It doesn’t even look like her." A different reaction questioned her expression, writing, "But why hold your mouth like that? To be sexy?"
