Move over, Essex. It's Chelsea's turn: Reality TV spotlight goes west

At first glance, they couldn't be less alike. One is a permatanned nightclub promoter from Essex, the other a polo-playing son of a diamond mining dynasty. But look beyond the orange streaks and signet rings, and Mark Wright and Francis Boulle have something in common: they are the stars of a new breed of reality TV, the mocku-drama.

While Wright is already notorious as the "star" of The Only Way Is Essex, Boulle is likely to join him as one of TV's guilty pleasures. He is the 22-year old entrepreneur tipped to be the standout performer of Made in Chelsea, an eight-part series starting next week.

Boulle has already made headlines by being linked to the Harry Potter star Emma Watson, and regularly appears in Tatler's Little Black Book, a list of the most desirable singletons.

The question remains how audiences will respond to the antics of Boulle and his friends. Reactions to The Only Way Is Essex (or Towie, as it is also known) ranged from disbelief to criticism from other residents of Essex, who said it misrepresented their county.

A million viewers tuned in for the new series of Towie last month, and as many are expected to watch the debut episode of Made in Chelsea next week. Though they explore two very different worlds, the programmes share the same formula, following the lives of extraordinary young people. While previous reality TV shows have sought to be as "real" as possible, the makers of the latest wave do not pretend that many of the scenarios are not invented. But the dialogue and jaw-dropping scenes that ensue are real.

The makers of Made in Chelsea are promising a glimpse into the privileged lives of eight trustafarians centred on London's Sloane Square. They say it's an English version of the US drama The Hills, the hit MTV show set in Los Angeles. Yet viewers over here are more likely to be reminded of The Only Way Is Essex. This was the show that brought us the vajazzle and confirmed the prejudices of anyone who thought Essex was the home of slappers and footballers.

What is certain is that the stars of both series seem set to penetrate the public conscience with their outlandish lifestyles. Wright, 23, is notorious for his footballer-style philandering and beauty regime.

It remains unclear how sympathetic to the privileged lifestyle the makers of the E4 show will be. But friends of Boulle are confident he will emerge unscathed. "Francis is very savvy and knows what he is letting himself in for," said one. "People might find him extraordinary, and his life certainly is. But for whatever reason, people are certainly going to tune in for more."

Made in Chelsea begins on 9 May on E4
