The Made In Chelsea star - who has now left the reality series - posted yet another envy-enducing snap from her honeymoon in Italy yesterday (21 Sept).
Looking stunning in a black cut-away swimsuit which accentuates her slim waist, Millie is clearly relaxed and happy as she enjoys time with her new husband Professor Green - aka Stephen Paul Manderson.
Captioning the photo as "paradise", Millie is clearly one happy lady.
Just one day earlier, she had shared a picture of her wedding ring with her Twitter followers.
She and rapper Pro Green got married at the beautiful Babington House in Somerset on 10 September, which she described as the "best day of my life".
They married in front of guests including Millie's ex-Made In Chelsea co-stars Rosie Fortescue and Caggie Dunlop and Professor Green's friend Lily Cooper.
