The two gorgeous girlies, both 33, joined a whole host of other superstars and headed to fashion designer Riccardo Tisci's birthday party on Friday night.
And it wasn't long before the former best friends made a beeline for one another.
Settling down together for a chat, Paris and Kim shared a joke which makes it look very much like there's no longer any tension between the pair. LOVES IT!
Kim shared the cute snap on Instagram and added: "Reminiscing about the 1st time we went to Ibiza in 2006! @parishilton it was so good to see you & catch up!! Loves it lol."
So, the girls grew up together and were firm friends from a young age. For a while, Kim worked as Paris's personal assistant.
But things got tense and a bit of rivalry is thought to have emerged between Paris and Kim.
However, from the look of this super cute snap, there's no problem now!
Kim cozied up to lots of other celebs on the night, too, and said online: "Mommy's night out #HappyBirthdayRicky."
She partied with models Kate Moss and Naomi Campbell, posting a series of snaps of her fun night out.
Kim said: "about last night #Givenchy #Ibiza @riccardotisci17 @iamnaomicampbell."
But our favourite has to be the picture Kim took before she left the house.
Look! Kanye's taking a nap! MEGA LOLS.
Kim simply said: "Side chicks be like…."
