LOS ANGELES, CALIFORNIA: Britney Spears has undoubtedly become one of the biggest Halloween costume inspirations in 2023 as she has rarely been out of news this year.

At the Casamigos Halloween party this past weekend, two prominent stars donned different versions of the pop sensation from her famous 2004 'Toxic' music video – Paris Hilton and Jessica Alba.

While Paris Hilton faithfully recreated Spears's unforgettable blue flight attendant uniform, Jessica Alba turned heads with a striking and daring transformation in a nude one-piece adorned with sparkling rhinestones, just like Britney's sensuous look in the video.

Jessica Alba nails Britney Spears' 'Toxic' look at Halloween bash

Alba chose to slip into a sheer bedazzled bodysuit that flawlessly mirrored Britney's iconic look from the 'Toxic' video.

Photographed as she arrived at the star-studded event, Alba's nude one-piece was adorned only with sparkling rhinestones, leaving very little to the imagination and revealing her flesh-colored lingerie underneath.

Alba's attention to detail was remarkable, and she even accessorized with silver peep-toe heels and a platinum blonde wig featuring curtain bangs.

Completing her transformation, she embraced the Y2K style with nude glossy lips, bronzed skin, and frosted eyeshadow.

At the Halloween event, Jessica Alba was accompanied by Baby2Baby co-CEO Kelly Sawyer Patricof, who also participated by channeling a classic Britney Spears look – the schoolgirl costume from her 1998 'Baby One More Time' music video.

While Jessica Alba's costume was a nude bodysuit, Britney Spears had herself revealed once that her diamond-covered ensemble was not an outfit at all.

In a 2016 interview with British talk show host Jonathan Ross, Britney disclosed, “That's not actually an outfit. Those are just hand diamonds painted on me. Well, glued on me.”

The host was in disbelief and sought clarification, asking, “Were they glued on your body? Or on a bodysuit?” Britney confirmed, "Glued on my body."

Fans joke about Jessica Alba mimicking troubled Britney Spears for Halloween

The star-studded Casamigos Halloween party saw Alba's jaw-dropping transformation, but fans couldn't resist adding their playful and witty commentary to the mix.

One fan humorously quipped, "Where the knives at?" — a reference to a viral video posted by Britney Spears herself where Britney showcased her unconventional dance moves with sharp butcher knives in each hand, twirling and playfully wielding them with a smile on her face.

Another fanwrote, "I was expecting spinning and knives."

"Jessica Alba nailed her Halloween costume as Britney Spears! Check out her incredible transformation for some serious '90s vibes!," commented another.

Another wrote, "Jessica got that hotness"

One commented, "Finally, we are able to see that outfit again."
