The stars certainly know the Hamptons are where it's at for chic getaways, but since not all of us receive invites to the posh parties and premieres, here's the scoop on this ritzy summer retreat!

Our Luxaholic ears perk up at the mere mention of the word "Hamptons." Here's what you need to know to be in the know:

The string of towns that comprise the Hamptons are at the Eastern end of Long Island, 2.5 hours from NYC, with some of the best beaches in the world and the most luxurious homes imaginable.
