Simon Cowell's Syco Summer Party Was Typically Star-Studded

The celebs were out in force last night (18 July) for Simon Cowell’s annual blow-out, the Syco summer party.

At the top of the star-studded guest list was former ‘X Factor’ judge Cheryl Fernandez-Versini, who proved that she’s still a friend of the show - and its boss - when she was snapped on her way into the event, sporting a colourful ensemble.

A plethora of former ‘X Factor’ contestants from previous series were also in attendance at Lancaster House, including ex-runner up Fleur East, who was photographed in a “rock chick”-inspired outfit.

She was followed by fellow Syco acts, Ella Henderson, Reggie ‘n’ Bollie and current reigning ‘X Factor’ champion, Louisa Johnson.

The man himself was dressed… well… exactly as you’d expect him to be, to the point we sort of wish we’d put a bet on it.

Dressed - you guessed it - in an ill-fitting white shirt and what appear to be stonewash blue jeans, he posed outside the venue with his long-term partner, Lauren Silverman, who sported a white dress for the occasion.

Among the more surprising guests at the party were former ‘X Factor’ winner James Arthur (who doesn’t exactly have the best relationship with Simon), ‘The Chase’ host Bradley Walsh and, of course, Lizzie Cundy.

Outfit of the night, naturally, goes to Sinitta, who posed with music producer Naughty Boy underneath a parasol in one of the finest photos we’ve ever clapped eyes on.
