The former Made In Chelsea
star shared a snap of her beauty look. "Hair and make-up done. Nearly ready for take off! @virginatlantic," she wrote.
After the Manchester event, she headed straight back to London where she is due to visit her husband Professor Green's West End club Ink. "Thank you to my amazing glam squad today @Bumbleandbumble @macdanni keeping my hair in for tonight! @INKLDN x"
Millie recently came back from her honeymoon and immediately was forced to deny pregnancy rumours that were circulating.
"Pregnancy rumours are just that.. We are far too busy enjoying each other right now", she said.
The denial came a day after she and Professor Green made their first official appearance as married couple.
Shortly after arriving back from their honeymoon, the newlyweds visited INK for a night out.
