Are you ready to take a stroll down memory lane?!
Kim Kardashian and Paris Hilton were giving us serious Deja vu this weekend as the former besties proudly proved they are still the party girls we once used to know and love.
The reality television stars celebrated on Saturday night at Paris' belated birthday party, which was also a St. Patrick's Day bash.
Kourtney Kardashian also made an appearance for her friend's 38th birthday, which was actually last month in February.
But it's Paris Hilton so obviously she can celebrate her birth whenever she wants.
Kim, of course, took to her Instagram Stories to show off the lavish party.
She included pictures and videos from the event, one which showed off Paris wearing a sparkling silver catsuit and posing at the bottom of a staircase next to a presentation of Tiffany blue balloons.
Paris quickly reposted the clip, writing, "Loves it @kimkardashian."
"Love you @kimkardashian," she added. "So much fun celebrating my birthday with you at #ClubParis."
Kim also posted another video which said, "Happy birthday Paris, even though your birthday was [a] month ago. But she deserves it."
The reality stars have been friends since they were children and Kim famously helped Paris rearrange her closet on her reality show The Simple Life.
Since being Paris' closet organizer, the besties took over the 2000's party scene and you really couldn't see a paparazzi photo without the two completely attached at the hip.
Some mistook her fashion-forward bestie for her assistant, which was so not hot, but quite hilarious to think about now.
However, several years later after many vacations, parties and red carpet events, the friends turned frenemies very quickly.
Some say it was due to Paris often making fun of and talking s--t in interviews about her so-called bestie, while others believe it was due to Paris' jealousy at the Keeping Up with the Kardashian star's rising fame.
Anyone remember the show Paris Hilton's My New BFF??
Either way, the two only have nice things to say about each other now and praise one another's... success.
(M.ind you, Paris Hilton is now a DJ)
In 2016, Kardashian and Hilton officially reunited at Kris Jenner's annual Christmas Eve Party.
And Paris also attended the more recent holiday event, this time put on at Kim and husband Kanye West's home.
Kanye tweeted a video of Kim and Hilton sledding, captioning it "Bff."
We knew the love was real though when the Kardashian-Jenner matriarch shared a special message for the heiress, saying "Christmas Eve with this gorgeous girl who taught me when she was just a little girl, that blondes really do know how to have a LOT of fun!!! Love you Paris @ParisHilton #family #christmaseve #tradition."
The two are on such good terms that Paris even dressed up as a "Kim Clone" in an ad for Kanye's Yeezy Season 6 campaign back in 2018.
So yeah, It's very clear that their friendship is back in business!
