The stars of reality TV hit The Only Way Is Essex will star in a special live episode this Christmas.
Show bosses have reportedly put a booze ban in place in a bid to avoid any drunken mishaps by the cast who regularly appear out and about in different Essex night-spots in the ITV2 show, known to fans as TOWIE.
Sam Faiers said: "I'm really excited but so so nervous. It's going to be an amazing experience. Who knows what will happen... especially in Essex."
Co-star Mario Falcone said the cast would be "completely out of our comfort zone".
There will also be a one-off Christmas special on ITV2 the day before the live episode.
Soaps including Emmerdale and Coronation Street recently filmed live episodes to celebrate landmark shows - their 40th and 50th anniversaries respectively - but they are notoriously difficult to film and mistakes are easily made.
TOWIE's Lucy Mecklenburgh admitted the nerves would get to her, saying: "I don't know how we're going to do it. It's crazy. Personally I'm just really scared but I know it's exciting too."
There are rumours that former stars such as Amy Child could return for a cameo on the festive episode, although former couple Mark Wright and Lauren Goodger are not on TV bosses' wishlists.
Amy, who left the show after the first two series, starred in Celebrity Big Brother in 2011, and featured in her own fly-on-the-wall reality TV series It's All About Amy, which ran for one season.
