Millie Mackintosh has joined in with the likes of Rihanna and Miley Cyrus and showed us all she has to offer by flashing a lot of bum.
The Made In Chelsea star decided to 'be Beyonce for day' and try on a dreamy Julien McDonald dress.
With all her epic wall squats, Mils was not about to keep that bikini bottom under wraps.
And,as we know, if you're going to be a pop star for a day you just have to expose some skin.
Even Pixie Lott got in on the action last night with her nipple flashing crop top.
At least Millie's doing it in the classiest way - of course.
