Dressed in a flowing white gown with dramatic styling, Aguilera turned heads the moment she arrived. The sheer, floor-length dress featured a corset-style bodice laced tightly at the front and cinched at the waist, giving structure to the otherwise ethereal fabric.

A cape draped from each shoulder added to the ensemble’s goddess-like vibe, while the neckline plunged into a deep V, framed by delicate diamond jewelry.
Her signature platinum-blonde hair was styled in long, beachy waves with a tight braid pulled into a high half-up ponytail. Her makeup emphasized bold lashes, defined brows, and a deep rose lipstick.

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?”
In contrast, another viewer offered a more favorable take, adding, “She had REALLY good work done.”

Other responses, while less direct, suggested Aguilera’s look left many confused. Several remarked she appeared unrecognizable, with some questioning whether it was even her.
One comment speculated she looked deeply unhappy, while others critiqued the overall styling — calling out her long hair extensions and the gown as overly flashy or mismatched for the occasion.
This is not the first time Aguilera’s appearance has caused a stir on social media. On January 18, 2025, the musical superstar stunned netizens with her svelte physique and youthful appearance at the Joy Awards in Saudi Arabia.

She stole the show in an eye-catching outfit designed by fashion powerhouse Balmain. The pop icon radiated confidence in the fashion brand’s Pre-Fall 2025 sequined trompe-l’oeil skirt paired with a crisp, tailored blouse — a look styled by renowned fashion stylist Chris Horan.
Aguilera accessorized with sleek black sunglasses, exuding effortless glamour and sophistication. Her platinum blonde hair was elegantly styled, complementing the outfit’s modern and edgy vibe.

“Looking good—she’s lost a lot of weight,” one fan observed, while another swooned over how fit Aguilera looked. Joining the chorus of compliments, a fellow admirer gushed, “She’s so slim and looks amazing 🔥.”
Others offered more neutral observations about Aguilera’s appearance. One user noted, “She looks like she’s in her 20s,” while another remarked, “She’s aging backwards.” Someone else added in awe, “Didn’t even recognize her! 😮”

On the other hand, some users expressed dissatisfaction with Aguilera’s style and overall appearance. “Looks so… soulless. And the sunglasses just make it worse,” one critic remarked.
Another commenter added, “Her style really hasn’t evolved in the past 20+ years. It’s time to let go of the overly bleached hair, 2008-era clothing, and heavy makeup.”

More scathing opinions followed, with yet another person expressing, “I hate everything about this. The brittle blonde. The overlined lips. The accessories. The outfit. The bad tan. The lack of tailoring…”
Another pointed critique came from someone who questioned, “Is that a skirt printed to look like a different skirt? Also, I would never have guessed that’s Christina Aguilera in a million years.”

Regardless of the divided social media opinions, Aguilera’s presence at the event added to the star-studded vibe of the prestigious affair.
Known as a celebration of joy and entertainment, the Joy Awards shines a spotlight on an array of influential figures, including music stars, cinema icons, accomplished athletes, and other individuals who are making a meaningful and positive impact on people’s lives.
The event honors excellence across various categories, such as Personality of the Year, Lifetime Achievement, Joy Honorary, Diamond Entertainment Industry, and Winners.
Over the years, A-list celebrities have won awards like the Personality of the Year title, including Eva Longoria in 2024, Sofia Vergara in 2023, and Salman Khan in 2022.
Joining Aguilera at the prestigious affair was her partner, Matthew Rutler. Rutler complemented Aguilera’s show-stopping look by donning a classic suit that exuded sophistication. Together, the pair made a striking duo at the event.

The pair’s love story traces back to the set of “Burlesque” in November 2009, where Aguilera and Rutler first crossed paths. In October of the following year (2010), Aguilera filed for divorce from her first husband, Jordan Bratman.

During a past interview, the singer opened up about the budding connection she and Rutler shared during the filming process.
“Matthew is a special person. We had a really strong friendship on [sic] the movie. He’s the kind of person you could spend hours on the phone talking to, and all of a sudden it’s daylight,” divulged Aguilera.

Despite their instant bond, Aguilera shared that she approached the relationship with caution, mindful of her recent separation. “I’m not trying to jump into anything. I just left a five-year marriage. I’m taking it slow and trying to be happy,” explained the artist at the time.

Although they got engaged several years ago, the couple has felt no urgency to walk down the aisle. In 2015, Aguilera opened up to People about their decision to pace themselves.
“Having just moved into a beautiful new home we call ‘the Sanctuary,’ having a baby, and now being so excited to get back to work [on ‘The Voice’], I have my hands full, and am not in a rush to set a date,” shared Christina Aguilera.
