The former Celebrity Big Brother star oozed glamour on the blue carpet in Leicester Square before heading to the cinema to watch Night at the Museum: Secret of the Tomb.
Casey looked totally gorgeous in a beautiful forest green gown, which featured a flowing floor-length skirt and a sexy black lace bustier which enhanced her voluptuous figure.
We thought Casey's dress would be a pricey designer number, but it's actually from online retailer Rare London and is currently reduced from £59 to £41.30.
To glam up her ensemble even further, the starlet toted a patent Saint Laurent clutch with gold tassel detailing while accessorising with a dainty necklace and an elegant silver bangle.
Her dark brunette locks flowed past her shoulders in a straight yet voluminous style, and she enhanced her chocolate peepers with a slick of winged-out liquid liner.
She ditched the bold lippy and instead kept her pout totally natural, finishing her look with a touch of bronzer on her cheeks teamed with fluttery jet black lashes and structured brows.
Looking lovely, Casey!
