And with the five handsome lads doing the red carpet rounds that evening, Ashley ensured she was dressed to the nines for the special event.
The model proved you don't need a designer bank balance to look gorgeous as she shimmered in a dazzling sequin dress, £65, from Lipsy.
She amped up the sparkle with a diamanté statement necklace, adding red peep-toe wedges and a mock-croc clutch.
And we can't get enough of her pretty make-up look either, which featured peachy cheeks, a slick of nude lippy and smoky grey peepers.
Red carpet glam on a budget? Now that's what we like to see!
