The trio of glamourpusses looked fabulous in their ballroom frocks as they took to the red carpet at the event held at the show's new studios in Elstree, London.
'Countdown' maths whizz Rachel led the pack in a Marilyn Monroe inspired dress, complete with ringlets in her hair.
Abbey dazzled in a glitzy one-shoulder silver dress, finished off with a feather trim, while Sophie was a sixties siren with her hair in a beehive and wearing a silky white number.
They were joined by their fellow contestants golfer Tony Jacklin, broadcaster Vanessa Feltz, 'BBC Breakfast' host Susanna Reid, 'Dragons' Den' star Deborah Meaden, former 'Coronation Street' star Natalie Gumede, rugby player Ben Cohen, actress Fiona Fullerton, Hairy Biker Dave Myers, Hollyoaks' Ashley Taylor Dawson, 'Casualty' star Patrick Robinson, Waterloo Road's Mark Benton and designer Julien Macdonald as they spoke to the nation's press.
Tess looked stunning in a backless gold and black gown, as she larked around with Brucie in front of the cameras.
Earlier this week, she admitted she fears the hit BBC ballroom show has a shelf-life, as it will run out of top-notch celebrities willing to compete.
