The young women cut stylish figures as they clearly dressed to impress for the occasion.
Gemma wore a conservative black jumpsuit, which were embellished with a retro, cut-away collar in white. She capped the look with some black, semi-sheer sandals.
Meanwhile, Hannah - who recently starred in Walking on Sunshine with Leona Lewis - opted for a daring approach.

Clearly keen to flash some flesh, she wore a light grey summer dress with a plunging neckline and figure-hugging design.
Opting for a more femme-fatale approach, she parted her blonde hair down the middle and added a flash of bright red lipstick.
Taking care to add detail, she also wore some intricate earrings and a pair of strappy shoes.

Cutting a more classy figure, however, was Anna Friel.
The Rochdale-born star, whose hit films include Me Without You and Limitless, looked effortlessly demure in a black and white, sheer polka-dot dress.
Interestingly, the number featured a ruffled detail on the chest - and a see-though panel.
