It's 2006 all over again!

Former BFFs Paris Hilton and Kim Kardashian reunited in Ibiza over the weekend, taking their first photo together in 5 years.

The two were spotted at Givenchy artistic director Riccardo Tisci's birthday party on Friday night, with Kim sharing a pic from the festivities on Saturday.

"Reminiscing about the 1st time we went to Ibiza in 2006! @parishilton it was so good to see you & catch up!! Loves it lol," she wrote along the the photo, showing the two sitting side by side inside the bash.

The duo used to be inseparable back in the day, before they had a falling out once Kim's star started to rise.

Back in 2008, Paris slammed Kim during a radio interview -- saying her infamous booty "looks like cottage cheese stuffed in a trash bag."

Paris later apologized for the remarks, saying "I was just joking around and I made a stupid joke, I felt really bad afterward, so I contacted Kim and apologized. It was a silly thing to say. Kim's hot."

Looks like all's forgiven now, right?
