Despite swirling rumors of a feud between former best friends Paris Hilton and Kim Kardashian, they were all smiles when they bumped into each other in Cannes. The two met at the amfAR gala Thursday at the Hotel do Cap-Eden-Roc in Antibes, and witnesses — who were hoping for a reality-TV-style catfight — said the pair “hugged, smiled and chatted for a while.” A source added, “They really have no problem with each other; it has been a long time.”
