Kourtney Kardashian and Stephanie Shepherd filled their backpacks with 'candy and condoms' on Halloween

Nothing like a little cheeky Halloween fun.

Kourtney Kardashian and pal Stephanie Shepherd donned one of the best celebrity Halloween costumes this year when they dressed up as Fook Mi and Fook Yu from "Austin Powers" to go to Kendall Jenner's house party. Their epic getups channeled the infamous characters' Harajuku school girl style, complete with pink-and-blue hair extensions, over-the-knee socks and oversized backpacks.

On the pink carpet at the 2018 Victoria's Secret Fashion Show on Thursday night, Shepherd made a hilarious reveal exclusively to AOL about the two-person costume that nobody realized.

"We filled the backpacks with candy and condoms," she told AOL's Gibson Johns with a laugh. "It was awesome."

Shepherd also told us that the pair has been thinking about dressing up as the iconic twosome for two years now.

"She has an amazing stylist, Dani Michelle, who made [the costumes] custom," she said. "Can you believe?! Honestly, Kourtney and I had dressed up as a bride and groom two years ago, and I got so excited, so I was like, 'What else could we be?' We've literally been sitting on that costume for two years, and we finally just did it and put it together."

Shepherd, who used to work as Kim Kardashian's personal assistant, has grown very close with the famous family over the years, but she checked off a major "first" at the Victoria's Secret show this week.

"I've actually never even seen Kendall walk in a show before," she told AOL. "It’s crazy! I’m so excited to see Kendall walk."

The 2018 Victoria's Secret Fashion Show airs on December 2 at 10 p.m. on ABC
