On their own, celebrities have a magnetic draw that lands them on the covers of magazines, in gossip columns, and in conversations in living rooms and online forums across the world. When the world's biggest stars gather together, however, it's hard for even the most uninterested onlookers not to take notice.
From legendary posses like the Rat Pack of old to the leading ladies of “Saturday Night Live,” and other star-studded crews of today, celebrity friendships are often the ultimate life of the party. Cameras flash when they're seen in public; when they hang out behind closed doors, the masses wish they could be flies on the wall. Some of the biggest celebrities in the world see their star power magnified by cozying up, collaborating, and partying hard with their rich and famous peers. Sometimes they gather on yachts with nine-figure price tags, in VIP sections of the world’s hottest hangouts, or in exotic destination paradises. Other times, however, the world's elite cliques spend time doing everyday things or meeting to discuss upcoming projects. Many times, though, the celebrity elite live up to their reputations with all-night debauchery and hard partying in outrageous elegance.
Here's a look at the coolest cliques and crews in the exclusive worlds of rock stars, movie stars, models, Instagram celebrities, authors, artists, television heroes, and reality show stars who are famous simply for being famous. Although most of the multitudes will never share a drink or a dance with them, everyone can live vicariously through them.
