Millie, 24, joined Pro Green and a group of friends for dinner at swanky London eatery Paradise and was happy to pose for pictures with her man.
The former Made In Chelsea star was dressed to kill in a gorgeous grey patterned frock and killer suede boots to match.
She left her hair loose and in natural waves and topped off her outfit with a pair of blue dangly earrings.
Birthday boy Pro Green - real name Stephen Manderson - meanwhile looked super smart in an all-black ensemble.
Luckily for Millie, he had also invited along her best friend and former MIC co-star Rosie Fortescue.
Despite it being her hubby's birthday, Millie looked like she had a great time having a girly chat with her bestie over a glass of wine!
