What's a girl group to do when they realise they've just scored their first No.1 hit single (with What About Us, btw)? Get dressed up to the nines and hit the town, of course.
And that theme continued as they learned of their success at the Radio 1 studios, before heading out to celebrate at upmarket eatery, Zuma, and to dance the night away at the Amika nightclub afterwards.
While Vanessa and mum-to-be Rochelle kept it elegant in LBDs, Una bared her midriff in a purple embellished cutout dress with a split, Mollie made the most of her perma-tan in a gorgeous white shift dress, and Frankie showed off her pins in a two-tone frock with a metallic-silver skirt an tight white top.
Whose look was your fave?
