We spoke to Millie just last week after she'd returned from a holiday in LA, sporting an all-natural golden tan. But it seems she's now been giving her fading glow a little helping hand since being back in the not so sunny UK!
The former Made In Chelsea star has revealed she can't get enough of Cocoa Brown Lovely Legs Spray in Medium Bronze.
The product works as make-up for legs, covering any flaws while also delivering a dose of healthy, water resistant colour, which will wash off with soap once your night's over.
But the best part? It costs a very reasonable £8.99 - hooray!
Instant tans are fab if you're heading for a night out and need to add a glow in a matter of minutes. We also like the new Rimmel Sunshimmer Instant Tan + BB Perfector in Light Matte, £6.99, which offers the benefits of a BB cream including added moisture to help soften and smooth your limbs.
And if you really want to perfect your bod for a night out, make-up artists swear by using MAC Face and Body Foundation, £27, when primping and preening celebs for a red carpet event. This won't make you look tanned but it will help make your skin look flawless - just brush on any blemishes you want to disguise.
Another great cheat to make your pins look supermodel-worthy is to apply a touch of shimmer (MAC Mineralize Skinfinish in Soft & Gentle, £22, is great) just down the very centre of your pins. This will help make them look slimmer.
You can even go the whole hog by contouring your legs too - just take a matte face powder a couple of shades darker than your skintone and, using a large fluffy brush, sweep down the sides of your limbs to create a shadow.
Sorry Mills - you're no longer the only one with perfect pins!
