The star's hair was pulled back into a ponytail, exposing her 'Mrs C' tattoo, inked on the nape of her neck during her short-lived marriage to footballer Ashley Cole.

Cole will kick off her 'A Million Lights' tour in Belfast on October 3, with Holloway set to join as a backing dancer. The pair have been rehearsing hard and recently performed on the Danish Voice.
She tweeted earlier this week: "This time next week I will be soundchecking for the first night of my #AMillionLightsTour .. Who's ready ???"
