Millie was spotted yesterday (17 October) leaving luxury London hotel Claridge's with her BFF Rosie Fortescue after spending the afternoon with her.
The girls caught up on the latest gossip and were both seriously dressed to impress. But would we expect anything else?!
Quality Street heiress Millie, who married Professor Green in September, was rocking a seriously stylish pair of thigh-high boots, which seem to be all the rage this season.
She teamed her boots - thought to be from Russell and Bromley - with a plum coloured pencil skirt, matching tailored jacket and black top featuring a saucy lace panel down the front.
Millie topped off her look with a black fedora hat, which partly covered her new fringe - and a black shoulder bag with gold chain.
Rosie, meanwhile, was also looking hot to trot, wearing thigh-high boots - this time from Dune - a black lace skirt and top and a long leather jacket. She was also sporting a fedora on her bonce and toted a designer bag in the crook of her arm.
The girls no doubt had a great afternoon, however Millie had earlier joked that her outfit may have given her taxi driver the wrong impression.
She tweeted: "Pretty sure my cab driver thinks I'm a hooker.. Wearing thigh-high boots in the middle of the afternoon on the way to Claridge's.. Ooops."
What does he know, Mills!
