Here's our guide to the most decadent and celebrity-heavy events of the season...
Cartier Queen's Cup
When? 15 June at Guards Polo Club What? The A-list sip on Cartier's specially blended champagne, as international polo teams vie for the chance to win the yearly silver cup, presented by the Queen herself. Expect Hollywood royalty, aristocrats and hot young A-listers to be out in spades. Who? Sharon Stone, Princess Beatrice, Katherine Jenkins, Charlotte Casiraghi, Jack Whitehall, Edie Campbell and Dita Von Teese.
Veuve Clicquot Gold Cup
When? 20 July at Cowdray Park Polo Club What? The final of the British Open Polo Championship is played out in front of a glamorous crowd of A-listers and fashionistas (not to mention the odd Made In Chelsea cast member). The champagne is free-flowing in the VIP area (naturally), where the likes of Daisy Lowe have been known to hit the decks to keep the well-heeled crowd dancing well into the night. Who? Jodie Kidd, Charlotte Dellal, Jodie Kidd, Lawrence Fox, Chris O'Dowd, Mollie King and Tinie Tempah.
Glorious Goodwood
When? 29 July - 2 August at Goodwood Racecourse
What? The iconic horse racing event attracts the best jockeys in the world and a glamorous crowd (particularly on Ladies' Day), who make Pimms-fuelled bets and enjoy live music in all the enclosures. Extravagant hats are basically a requirement.
Who? Zara Phillips, Sophie Ellis-Bextor, Bill Nighy, Anna Friel, Kelly Brook and Michelle Rodriguez.
Wimbledon
When? 23 June - 6 July at The All England Club
What? At least this is one event we nobodies can get fully involved with. But there's no 3am queueing for the A-listers who bag an invite to the Royal Box for a front row view or entry to the Evian Live Young Suite, where there's a champagne reception, gourmet lunch and ping pong tables for those who want a little taste of the action.
Who? Victoria Beckham, Naomi Campbell, Bradley Cooper, Gerard Butler Holly Willoughby, the Duchess of Cambridge, Suki Waterhouse and Nick Grimshaw.
Audi International Polo
When? 28 July at Guards Polo Club What? It's not all drinking and flirting at the Audi-sponsored tournament, where Prince Charles and other serious polo fans dress up to catch some proper action on the field. Anyone who's anyone goes to the exclusive after party pop-up, hosted by A-list London club Boujis, where the likes of Pete Tong and Groove Armada are left in charge of the merriment. Who? Eddie Redmayne, David Gandy, Zoe Saldana, Julien Macdonald, Laura Whitmore and Billie Piper.
Henley Royal Regatta
When? 2 July - 6 July What? The Regatta is basically five days of buff rowers racing up and down the Thames. Plonk yourself on a deck chair with some bubbles and crustless sandwiches or head over to the Redgrave VIP bar to lounge on a day bed with a pitcher of Pimms and listen to the DJs that play throughout the day and on into the night. Who? Princess Anne, Daisy Lowe and Kelly Osbourne... plus a whole load of preppiness.
Royal Ascot
When? 17 - 21 June at Ascot racecourse What? The highlight of this racing event in Berkshire has to be Ladies' Day, which is worth the ticket price alone just to get a close-up look at the show-stopping hats (both amazing and horrendous). One word of warning though: the dress code is strict. Who? Ant and Dec, David Walliams, Lara Stone, Katherine Jenkins, Joanne Froggatt, Jenson Button, Ronnie Wood, Elizabeth Hurley, Joan Collins and ALL the royals.
