Kim Kardashian, Former BFF Paris Hilton Reunite For Girls' Night: 'So Much Fun'

Kim Kardashian and former best friend Paris Hilton reunited for a girls' night and had a blast during their Friday, Sept. 18 outing.

In videos they shared on Instagram, Hilton and Kardashian are seated inside a car as the "Keeping Up With the Kardashians" star holds up a camera and talks to fans. The two reality stars, who were close pals in the early 2000s, wore matching outfits for their get-together.

"We're just hanging out just a fun day, me and Paris. If you haven't seen her documentary on YouTube, you guys should check it out. Uhmmm that's it!" Kardashian said in one video Hilton shared on Instagram.

"That's it," Paris said, before they broke into giggles.

"Loves it," Hilton wrote in the caption. "So much fun hanging out today KimKardashian."

Fans of Kardashian and Hilton flocked to the posts, leaving sweet comments for the pair. Some also commented about Hilton's documentary.

"Your YouTube doc was amazing girl I relate to you in so many ways. Stay strong keep inspiring," Mandy Leon, a professional wrestler, commented.

"Watched 'This is Paris' yesterday. I used to know so little about you, but now I turn to have so much respect," a netizen wrote.

"You are teaching me the definition of working hard. Love you so much!" another fan commented. "Truly wishing for your happiness and the best for your future endeavors. Love from Indonesia, xoxo.”

Hilton and Kardashian formed a close bond during the time the heiress was a client of the reality star's closet organizing business. They were often spotted out and about in the 2000s but later drifted apart.

In 2018, Hilton joined the Kardashians' Christmas party, and Kanye West shared a video of them sledding together on Twitter.

"Bff," he wrote in the caption.

In an interview with The Sunday Times last month, Hilton revealed that Kardashian influenced her decision to freeze her eggs. The KKW Beauty founder even recommended her own doctor to the heiress.

"I had a really amazing conversation with Kim [Kardashian] about it," Hilton said. "She introduced me to her doctor, and I was so inspired by her to actually do it. I think every woman should do it because you can really control it and not have that ‘Oh my God, I need to get married.'"
