The former Made In Chelsea star is just back in the UK from a holiday to Portugal where she enrolled in Jason Vale's Juice Retreat, a juice, yoga and fitness retreat in the countryside.
After making us envious with Instagram snaps of herself looking chilled out in the sunshine, it was back to reality for Millie today, as she popped to a vintage store in Notting Hill, London, to browse the racks.
Millie looked gorgeous in ripped jeans, ankle boots and a striped top, adding a fluffy black coat to keep the chill away and an oversized Louis Vuitton tote for extra glamour.
It hasn't been the easiest start to 2016 for Millie, who announced last month her marriage to Professor Green had ended. In a joint statement, the couple said: "It is with sadness and regret that we confirm our separation. It is a mutual decision, we still care deeply about each other and would like it to be known it is on amicable terms and we wish each other well."
They had married in Somerset in 2013.
In her last interview before the split was confirmed, Millie told our colleagues at Women's Health: "I never wanted to be in a relationship that was just in the papers or a relationship that I benefitted or made money from. That wouldn't sit well with me."
"I've never done a tell-all about my relationship and I won't," she added. "I just get on with my life."
