The E4 show will return in the spring with a new ten-part run, Channel 4 announced today (November 21).
A 90-minute Made In Chelsea Christmas special has also been ordered and will air during the festive season.
The show, which follows the lives of wealthy socialites such as Caggie Dunlop and Spencer Matthews, has averaged 1m viewers for its second series.
Channel 4's commissioning editor David Williams said: "With such a loyal audience tweeting, checking in and following the lives of our new TV stars, it's fantastic to be once again returning to the hallowed streets of the Royal Borough of Chelsea."
Meanwhile, the show's executive producer Sarah Dillistone said she was "delighted" with the success of the show, adding: "We look forward to bringing new bed-hopping, name-dropping, champagne-popping characters to series three."
The news comes shortly after E4 unveiled the cast of its new structured reality show Desperate Scousewives.
The second series of Made In Chelsea will conclude tonight at 10pm on E4.
