The Made in Chelsea beauty looked drop dead gorgeous in the stunning bright yellow dress, that showed Spencer Matthews exactly what he's missing.
Lucy wore a ruched one-shouldered mini dress from Gorgeous Couture, £134, which showed off the star's amazing figure.
Yellow isn't the easiest colour to wear but it looked stunning with Lucy's gorgeous bronze tan and glossy brunette locks, which she wore in a simple centre parting for the dinner date in west London.
Lucy wore minimal make up to complete her sophisticated look, and looked fresh-faced and glowing.
She competed her look with a classic black Prada handbag (swoon!) and black and white wedges - the perfect way to flaunt her tanned, toned legs!
Hot dress + hot date? We reckon Lucy's nailed the perfect heartbreak remedy!
