She teamed the gown with heels by Rene Caovilla and jewels by Mappin and Webb.
She shared a photo of her ensemble on Instagram, writing: “This is Big Brother… Please do not swear. See you on @dancingonice at 6:20 Tonight we celebrate the best dance styles ever!”
She also sported a chic up-do, with tendrils around her face, marking a variation from her current signature bob.
The episode saw Coronation Street star Claire Sweeney skate off the ice after she failed to impress with her burlesque-inspired routine after she sprained a rib.
Comedian Lou Sanders was saved in the skate-off, despite a low-scoring waltz.
Dancing On Ice continues on ITV next Sunday.
