While the ladies have had their differences in the past, it seems Paris and Kim are firm friends again. The Keeping Up With The Kardashians star posted a picture of the pair remembering the good times together 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".
Birthday boy Riccardo also posted numerous photos of his party on Instagram, including one of himself with Oscar nominee Jessica Chastain and another with rapper Diddy.
