Kim Kardashian and Paris Hilton ... friends once again after the former BFF's ran into each other in Ibiza.
Kim posted the picture of their reunion on Instagram with the caption, "Reminiscing about the 1st time we went to Ibiza in 2006! @parishilton it was so good to see you & catch up!! Loves it lol"
The duo used to be besties. One of the most epic videos TMZ ever shot was when Paris took her new best friend Kim -- whom we had never seen before -- to Hyde back in 2005. They sauntered past Paris' enemy/former BFF Tara Reid ... who defeatedly watched from behind the velvet rope as the duo entered.
But Kim got famous -- even more famous than Paris -- and the relationship went in the dumper. In 2008, Paris bashed Kim during a radio interview saying her butt "looks like cottage cheese stuffed in a trash bag."
Tara Reid ... there's still hope.
