Millie Mackintosh is a natural beauty as she goes topless aboard a yacht in Ibiza ahead of Riccardo Tisci's big bash

  She was amongst the creme de la creme of the fashion world who were invited to celebrate Givenchy designer Riccardo Tisci's birthday in Ibiza on Friday.
And in preparation for the A-list party Millie Mackintosh enjoyed a fun day out aboard a yacht surrounded by friends.
Making the most of the beautiful scenery, as well as the gorgeous weather, the uber fit star stripped down to just her bikini bottoms.
