Reunited at last!

Over the weekend Paris Hilton posted some sexy snapshots from her vacation in Ibiza, but it wasn't the bikini pics that caught our attention as much as it was the party photo of her with former bestie Kim Kardashian! The ladies (along with a slew of other celebs, including Justin Bieber) were in town to celebrate Givenchy creative director Riccardo Tisci 40th birthday, and Kim posted the pic first and wrote, "Reminiscing about the 1st time we went to Ibiza in 2006! @parishilton it was so good to see you & catch up!! Loves it lol."

Paris added, "So much fun with @KimKardashian this weekend at @AmnesiaIbiza. The first time we ever came to this magical island was together. Such an amazing trip! Great catching up with you too beautiful! #Regram."

Wait, so does this mean that the two will be palling around once they're both back in town? We're dying to know!
