The love for a certain memoir author of the hour was palpable at the Casamigos Halloween party in Los Angeles on Friday night, as several stars paid tribute to the inimitable Britney Spears with their attention-getting getups.

Leading the pack was Paris Hilton, who recreated Spears鈥 iconic blue flight attendant look from the 2003 (that鈥檚 right, 20 years ago) music video for the hit 鈥淭oxic.鈥

Hilton posted a video of the costume to her , writing in the caption 鈥淚n honour of our Queen鈥 and adding the hashtag #IconsOnly.

The appreciation between Hilton and Spears is mutual. In her recently released memoir 鈥淭he Woman In Me,鈥 Spears wrote that 鈥渙ne of the people who was kindest to me when I really needed kindness was Paris Hilton. So much of America dismissed her as a party girl, but I found her elegant.鈥

Hilton and Spears regularly made headlines in the mid-aughts, when they were seen going out on the town with Lindsay Lohan while Spears was going through her divorce and a custody battle with ex Kevin Federline.

鈥淪he saw that I had babies and that I was suffering from the breakup, and I think she felt sorry for me,鈥 Spears wrote. 鈥淪he came over to my house, and she helped me out so much. She was just so sweet to me.鈥

On Friday night, Jessica Alba also rocked a look from Spears鈥 鈥淭oxic鈥 video 鈥 the flesh lace and glitter bodysuit 鈥 while Baby2Baby co-CEO Kelly Sawyer Patricof joined her for a photo op dressed as Britney鈥檚 first iteration as the sultry schoolgirl from 1998鈥檚 鈥淗it Me Baby One More Time.鈥
