Leading the glamorous brigade was Rochelle Humes, who was tapping into the ubiquitous monochrome trend in a black and white dress. She topped off the look with poker-straight locks and bright red lips.
Also opting for classic black was Sophie Ellis-Bextor, who wore a semi-sheer, sparkly black gown that showed off her slender physique.
Opting for a more neutral palette was Naomi Campbell, who put her supermodel figure on display in a grey cutout, floor-sweeping gown, while Amber Le Bon channelled old Hollywood glamour in a nude, sparkling dress and side-swept locks.
Laura Whitmore went all-white in a halterneck creation that made the most of her curves.
New Strictly Come Dancing presenting duo Tess Daly and Claudia Winkleman walked the red carpet arm in arm, smiling for the cameras in their dark-hued gowns.
Millie Mackintosh, meanwhile, wore a gold and nude sparkling Julien Macdonald number that she accessorised with vampish purple lips.
