Millie went all out, getting seriously glammed up for an evening with her rapper hubby on Saturday (8 March).
Don't they make a cute pair?
Not one to swerve the chance to get dressed up, Millie spent a few pre-date hours searching for the perfect dress for her night out.
Her choice? Dior, obvs!
We're not entirely sure we could stretch to this number for our own nights out, but the floor-length, mint green dress is a real jaw-dropper.
Not to mention the plunging neckline, which Pro Green was no doubt pretty pleased about!
Sharing pictures of their evening on Instagram, Millie proudly added: "My dashing husband."
After a night on the tiles, Millie was clearly in need of a little pick-me-up the following day.
So she headed to a nearby pub for a serious Sunday roast, washed down with what looks like a glass of rose. Sounds perfect!
