Our favourite glamorous globe-trotting socialites are back in Chelsea and some new faces are on the scene. In this series, Andy Jordan and Stevie Johnson are quick to get settled into the Chelsea party circuit. There are some new girls-about-town as well: Sophia Sassoon and feisty Lucy Watson who's definitely going to ruffle some feathers. She's a self-confessed player so the girls and the boys had better watch out! Sophia has swapped her New York life for the elite streets of Chelsea and, despite being an ex-squeeze of Spencer, finds herself in a love triangle with best friends Proudlock and Francis. The question on everyone's lips is who will she choose? Suave newcomer Andy turns up the heat when he takes a shine to Spencer's long-term girlfriend Louise, and it seems like he won't take no for an answer! One thing's for sure, Spencer is not impressed. Series 4 sees long-time Chelsea chums, Cheska, Binky and Ollie as close as ever, with flatmates Ollie and Cheska forced to stand up for Binky as her fledgling relationship with Jamie is rocky from the very start. Gabriella is back too and, for once, she and Ollie are getting on... but will they be more than just friends again? The insults fly this series as the feud between Millie and Victoria continues; luckily debonair Mark Francis is there to offer a restorative glass of champagne, the Chelsea equivalent of a warming cuppa!
