With her blonde hair styled, full make-up and purple satin shoes to compliment her gown, Claire matched up to the sexy St Trinian's stars in attendance; Gemma Arterton, Tamsin Egerton and Kathryn Drysdale.

The former Brookside actress joined fellow celebrities Russell Brand, Tara Palmer-Tomkinson, Girls Aloud, Trinny Woodall, Colin Firth and Rupert Everett on the red carpet at the Empire Leicester Square.

But in stark contrast 24 hours later she had swapped the red carpet look for a an unfashionable Coleen McLoughlin-style velour tracksuit in purple, and worn down sheepskin boots to pick up the morning papers.

While she was paparazzi-ready at the premiere, poor Claire was clearly unprepared for her close-up first thing in the morning, outside her London home.

The former Chicago star popped into a newsagents and bought several newspapers - perhaps in the hope of catching a glimpse of herself on the red carpet the night before.
