The former Made In Chelsea star was spotted with her rapper hubby at V Festival 2014 in Chelmsford this weekend (16 August), where she lapped up the sun in Virgin Media's Louder Lounge.
Taking the opportunity to showcase her amazing wardrobe, Millie wore a vintage-style cream lace dress which she nipped in at the waist with a statement bejewelled belt.
The stylista - who is currently working on the launch of her own clothing collection - added an effortless vibe by throwing on a khaki safari jacket with rolled-up sleeves.
But of course it wouldn't be a Chelsea gal outfit without a luxe designer addition, and this time Mills opted for a pair of slouchy grey suede boots by Isabel Marant. We just hope she didn't walk in the mud with them!
Meanwhile, 'Lullaby' singer Professor Green showcased a much more casual outfit, wearing black jeans and trainers plus a T-shirt featuring a Rottweiler print.
The rapper also added a slogan baseball cap while ensuring he stood out from the crowd in a bright red raincoat.
It seemed Millie and Pro had a great time in the exclusive Louder Lounge, tucking into a lunch of hot dogs while strolling through the grass with their model friend Charlotte de Carle.
The twosome also headed to the Virgin Media Stage to watch their pal Lily Allen perform on Sunday (17 August), but of course beat the crowds by nabbing front-row seats by the side of the stage!
It's alright for some...
