Jessica Alba Channeled "Toxic" Britney Spears in a Jewel-Encrusted Nude Bodysuit for Halloween

She even wore a blonde wig.

As Britney Spears's new memoir continues to break records, the pop star is the person to be this Halloween. Just ask Paris Hilton and Jessica Alba, who both showed up at the annual Casamigos Halloween party over the weekend as two different versions of Britney from the singer's 2004 "Toxic" music video. 

While Hilton recreated Spears's iconic blue flight attendant uniform, Alba upped the ante and slipped on a sheer bedazzled bodysuit that mimicked Britney's naked look in the song's visuals. Photographed arriving at the star-studded bash, Alba's nude one-piece was covered in sparkly rhinestones from top to bottom and showed off her flesh-colored lingerie underneath. Alba accessorized with a pair of silver peep-toe heels and a platinum blonde wig with curtain bangs. The rest of her glam included a few Y2K signatures — including nude glossy lips, bronzed skin, and frosted eyeshadow.

At the event, Alba was joined by Baby2Baby co-CEO Kelly Sawyer Patricof, who also went as Spears in a schoolgirl costume, circa her 1998 "Baby One More Time" music video.

And though Alba's costume was undoubtedly a bodysuit, Britney revealed that her diamond-covered look wasn't an outfit at all. "That's not actually an outfit,” Britney said during a 2016 interview with British talk show host Jonathan Ross. “Those are just hand diamonds painted on me. Well, glued on me.” In disbelief, the presenter clarified, “Wow, were they glued on your body? Or on a bodysuit?” Britney confirmed, "Glued on my body."
