Christina Aguilera, 45, appeared to have barely aged as she stepped out in an outfit reminiscent of her 2002 'Dirrty' era at MISTR's second annual National PrEP Day Celebration on Sunday, October 11, in West Hollywood.
The mum-of-two attended the event at The Abbey Food & Bar, where several stars spotlighted HIV prevention and access to the medication PrEP. She posed in a black, sheer, figure-hugging dress over a tiny leather skirt, paired with matching thigh-high heeled boots.
Throwback to 'Dirrty' era style
Aguilera rose to stardom after releasing her debut single, 'Genie In A Bottle', in 1999, and has since recorded nine studio albums. Her 2002 hit 'Dirrty' marked a drastic image change for the singer, prompting fans to label her 'Xtina'.
The music video for 'Dirrty' featured her dancing in an underground boxing club wearing a bikini and PVC stockings. Leather chaps, scarf tops and ultra-low rise jeans were among her outfit favourites of that time, helping transform her from a cutesy Disney star to a pop diva.
At the 2026 event, Aguilera updated those style staples with mesh detailing and suspenders instead of chaps, bringing the look into the present while allowing her long blonde locks to flow freely as she pouted for photographers.
Fans react to youthful appearance
Writing in response to images shared to social media, one fan asked in shock: "Is that Xtina? My God she looks great." A second added: "For real Xtina photo looks like it was cropped from 1999."
A third commented: "She looks damn fine!" While a fourth X user agreed: "Xtina looks amazing!" Alongside Aguilera, National PrEP Day was also attended by Charli xcx, Kesha, Demi Lovato and Chappell Roan.
Aguilera's approach to aging
Unlike many celebrities who dodge the plastic surgery question, Aguilera has been an open book. In 2023, she partnered with Merz Aesthetics as an ambassador for Xeomin, an anti-wrinkle injectable similar to Botox, and has been vocal about relying on a "little help" to smooth fine lines while emphasising a natural look.
"I don’t want to have a frozen face," she noted, highlighting her desire to maintain her facial expressions for the stage. Aguilera has also pointed out how self-confidence can make you look radiant, embracing what she calls an "old school approach": "I’m really into feeling more self-assured as you get older. That's the thing to truly embrace."
