See Paris Hilton and Jessica Alba channel Britney Spears with their 'Toxic' Halloween costumes

Costumes this good should wear a warning.

Paris Hilton and Jessica Alba brought some major Britney Spears energy to the annual Casamigos Halloween party on Friday, donning legendary looks from the singer's "Toxic" music video. And luckily, they didn't both wear the same costume.

Hilton, a longtime friend of Spears, arrived at the event sporting the Grammy winner's classic blue stewardess outfit from the video, complete with dangling earrings, a flight pin, and a signature hat.

She also paid tribute to Spears in an Instagram video that featured her miming the pop singer's iconic "It's Britney, bitch" line before strutting down a hallway.

"In honor of our Queen," the "Stars Are Blind" singer captioned the clip. "Happy Halloween."

The Simple Life star wasn't the only one with Britney on the brain. Alba also took some "Toxic" inspiration for her costume, rocking a glittering nude bodysuit, a blonde wig, and sparkling silver heels — another look Spears pops up in for the video.

Alba's model pal Kelly Sawyer Patricof came dressed as Spears, too, channeling her "...Baby One More Time" music video look.

Hilton and Alba were only a few of the stars who showed up to the event. Justin Bieber, Austin Butler, Edward Norton, Kaia Gerber, Machine Gun Kelly, Megan Fox, Glen Powell, Chord Overstreet, and more also attended.

Spears reflects on her friendship with Hilton and Lindsay Lohan in her new memoir, The Woman in Me, writing that the trio's highly publicized nights out in the mid-2000s were "never as wild as the press made it out to be."
